R The Flight Crew Operating Manual (FCOM) provides operating crew members and flight operations engineers with information on the ATR 42-- 400/500 technical description, procedures and performances characteristics. It may be used as a crew manual for training purposes and flight preparation. FCOM mainly comprises : - manuel management in Part 0 - systems description in Part 1 - limitations with comments in Part 2 - procedures : normal, following failure and emergency, in Part 2 with comments - procedures and techniques in Part 2.02 - performances (conservative and simplified compared with AFM) in Part 3 - Special Operations in Part 3 - OEB (Operations Engineering Bulletin) : validated by the ATR Chief Test Pilot, their aim is to cover temporary equipment discrepancy. They are printed on pale green paper and are situated at the very end of FCOM. For any question, comment or suggestion regarding this manual, or technical documentation in general, we recommend to use following e-- mail :

[email protected]

stating at the minimum : - aircraft model(s) - manual(s) concerned - precise page(s) if applicable DEFINITION OF THE PAGE A page is defined by : - a reference : Part / Chapter / Section / page number - Example : 2.05.10 page 20. - an effectivity criterion determining the page sequence example : Equipment, Modification, Engine... A page with a given reference may have several sequences : example : 2.05.10 page 20 No criterion . . . . . . . . . . . Sequence 001 Mod XXXX . . . . . . . . . . . . Sequence 002 Mod XXXX + YYYY . . . . . . Sequence 003 All the sequences cover, for a given reference, all technical solution or variant for aircraft types covered by the manual. Airlines receive a part of these sequences to cover their fleet. A sequence can be valid for several aircraft but an aircraft can not have several sequences: an aircraft receives the page with the highest sequence among all pages for which it has a validity.

RECTO- VERSO The FCOM is published in recto-- verso paper AT5 format customized for each airline. In the LENP (0.08.00) List of Effective Normal Pages, when recto and verso are printed, each sheet is represented by 2 lines : - the first line concerns the recto. - the second line concerns the verso. If only recto sheet is printed, it is represented by only one line. Then for each sheet, we find the validity line with an expression containing one or several numbers which represent FSN (Fleet Serial Number) of aircraft for which this sheet is applicable. To understand the effectivity of the sheets, you must read : Example : XX0001-- 0003 = XX FSN0001 to FSN003 - - > 3 aircraft valid XX0001 XX0003 = XX FSN0001 and FSN0003 - - > only 2 aircraft valid In CRT (0.10.00), we find the list of fleet aircraft with FSN, MSN (Manufacturer Serial Number) and registration number. MANUAL UPDATING Your manual comprises 2 types of pages : - white pages or NORMAL pages - yellow pages or TEMPORARY pages These 2 families of pages have a separated management. NORMAL PAGES (white) For its first issue FCOM was published in “white” normal pages. Then on a yearly basis at the minimum, a normal revision is performed amending previous issue by revising pages (sheet replacement), creating new pages (sheet insertion) or deleting pages (sheet deletion). Detailed and exhaustive information for manual normal revision updating is in SNNP (0.07.00), Shipping Note for Normal Pages. Operator must refer to SNNP and new LENP to update properly its manual. SNNP lists all revised, created or deleted white sheets. LENP gives aircraft validity information for all concerned white sheets. It is important to note that the action given in SNNP is valid for the sheet (recto-- verso) not for one page. Normal Revisions are listed in LNR (0.05.00) List of Normal Revisions. Reasons of revision are highlighted in RNR (0.06.00) Reason of Normal Revisions. ATR 42 Model : 400/500

MANUAL UPDATING (cont’d) TEMPORARY PAGES (yellow) Between two normal revisions some subjects may present a particular urgency. In those cases we perform a Temporary Revision. It may concern only one customer or the whole fleet. All temporary pages at a given moment are listed in LETP (0.04.00), List of Effective Temporary Pages. Temporary pages are recto-- only pages. When a white page exists with the same reference, a yellow page is inserted in face or before corresponding white page and its content amends the content of white page. If there is no white page with the same reference, yellow page(s) is(are) inserted just after the last adapted white page or chapter. Detailed and exhaustive information for manual temporary revision updating is in SNTP (0.03.00), Shipping Note for Temporary Pages. Operator must refer to SNTP and new LETP to update properly its manual. SNTP lists all revised, created or deleted yellow pages. LETP gives aircraft validity information for all concerned yellow pages. It is important to note that the action given in SNTP is valid for the yellow page (no verso on yellow page). Temporary Revisions are listed in LTR (0.01.00) List of Temporary Revisions. Each operator has its own LTR as Temporary Revision does not necessarily concern all customer : TR01 for an operator may be equivalent to TR10 for another operator and TR20 for ENV. Reasons of revision are highlighted in RTR (0.02.00) Reason of Temporary Revisions. AIRCRAFT CONFIGURATION All ATR modifications having an impact on FCOM content are listed in LOM (0.09.00), List Of Modifications. As for LENP or LETP, aircraft validity are given under FSN values. We may consult CRT to have correspondence between FSN and MSN.

20.1 DESCRIPTION

(See schematic p 7/8)

Compressed air is bled from the engine compressors at the LP or HP stages. The pneumatic system consists of all the systems designed to supply air to the various aircraft systems, zones or engines, with associated control, monitoring and indicating components. It supplies under pressure air for air conditioning, pressurization and ice protection system. A protection against overheat due to possible leakage around the hot air ducts is provided. AIR BLEED - Air conditioning and pressurization The system is designed to : S select the compressor stage from which air is bled, depending on the pressure and/or temperature existing at these stages. S regulate air pressure in order to avoid excessive pressures Air is generally bled from the low compressor stage (LP). At low engine speed when pressure from LP stage is insufficient, air source is automatically switched to the high compressor stage HP. (This may occur on ground and during descent at F.I.). Transfer of air is achieved by means of a pneumatically operated and electrically controlled butterfly valve, (HP valve) which remains closed in absence of electrical supply : S when the HP valve is closed, air is directly bled from the LP stage through LP bleed air check valves. S when the HP valve is open, the HP air pressure is admitted into the LP pneumatic ducting and closes the check valves ; air is therefore bled from HP stage only, without any recirculation into the engine.

R

- Wing and engine de-icing. Air is bled from the HP compressor stage. Transfer of air is achieved through a pressure regulating valve which is electrically controlled. ISOLATION Downstream of the junction of the LP and HP ducting, air is admitted into the duct by a pneumatically operated, electrically controlled butterfly bleed valve which acts as a shut off valve. It includes a single solenoïd which locks the valve closed when deenergized. The bleed valve automatically closes in the following cases : - Bleed duct OVHT - Bleed duct LEAK - Actuation of associated ENG FIRE handle - Engine failure at TO (UP TRIM signal) - PROPELLER BRAKE selected ON (for left bleed valve only). In the absence of air pressure, the valve is spring-loaded closed regardless of electrical power supply. Note : During a starting sequence, the bleed valves opening is inhibited.

CROSSFEED The crossfeed valve installed on the crossfeed duct is designed to connect LH and RH air lbeed systems. - On the ground, it is always open except when both engines are running and propeller brake is disengaged. - In flight, the crossfeed valve is normally closed. This is a spring loaded closed, solenoid controlled, pneumatic shut off valve. The valve is closed with solenoid deenergized. LEAK DETECTION SYSTEM A continuous monitoring system is installed in order to detect overheat due to duct leakage and to protect the structure and components in the vicinity of hot air ducts : - Wing leading edge and wing to fuselage fairing, - Upper and lower fuselage floor, - Air conditioning pack area. In order to ensure rapid leak sensing, a Kevlar envelope is installed around the major part of the high temperature ducts to collect and direct leaking air to the sensing elements. The sensing system includes two single loop detection assemblies, one for the RH and one for the LH air duct systems. The sensing elements comprise a control lead (nickel wire) embedded in an insulating material and are integrated in an inconel tube connected to aircraft ground. Each sensing element is permanently subjected to the temperature of the compartment it protects. For any temperature higher than a preset value : 153°C (307°F) applied to a part of the sensing element, the resistance of the eutectic mixture rapidly decreases and the central lead is grounded. This results in an alert signal processed in a control unit which triggers illumination of LEAK It. After one second time delay, the associated pack valve, HP valve and BLEED valve (and GRD X FEED valve if the left loop is affected) are automatically latched closed. Note : In case of LEAK, the crew must consider the associated bleed system as inoperative for the rest of the flight. OVERHEAT CONTROL SYSTEM This system includes switches (thermal resistances) which are installed on the engines, near the HP compressors exit. These switches, which are duplicated for safety, ensure that the bleed valve and the bleed air shut-off valve are closed whenever any abnormal over temperature conditions occur. They operate at 274°C (525°F) and are controlled by the MFC. Note : In case of OVHT, the associated bleed system may be recovered after a cooling time.

20.1 DESCRIPTION The TCAS is an on-board collision avoidance and traffic situation display system with computer processing to identify and display potential and predicted collision targets, and issue vertical resolution advisories on the pilot's and copilot's TCAS vertical speed indicator (TCAS VSI) to avoid conflict. From the transponder replies, TCAS determines relative altitude, range, and bearing of any aircraft equipped with a mode C or S transponder. From this, TCAS will determine the threat using standardized algorithms. Outputs from the TCAS System are voice messages and visual displays on the TCAS VSI's for Resolution Advisories (TCAS RA's) and Traffic Advisories (TCAS TA's). The TA is informative and indicates potential threats. The RA displays a threat resolution in the form of a vertical maneuver if the potential conflict is projected to occur. Threat aircraft with mode A transponders will not provide altitude information : therefore TCAS will not issue resolution advisories for these threats. The TCAS will not detect aircraft without transponders. The TCAS is a single system installation consisting of : - one TCAS processor, - two high resolution bearing antennae (one top mounted and one bottom mounted), - two mode S transponders, - two modified TCAS VSIs each integrating traffic advisory display and vertical speed information, - one pylon mounted TCAS control box, - two overhead speakers for voice messages and associated wiring. Following definitions are intended to be used for TCAS operations : (A) Advisory : A message given to the pilot containing information relevant to collision avoidance. (B) Corrective resolution advisory : A resolution advisory that advises the pilot to deviate from current vertical speed, e.g., CLIMB when the aircraft is levelled. (C) Intruder : A target that has satisfied the TCAS threat detection logic and thus requires a traffic advisory.

(D) Mode S : Type of secondary surveillance radar (SSR) equipment which provides replies to mode A and Mode C interrogations and discrete address interrogations from the ground or air. (E) Preventive resolution advisory : A resolution advisory that advises the pilot to avoid certain deviations from the current vertical speed because certain vertical speed restrictions exist. (F) Proximate traffic : Nearby aircraft within "850 ft and 6NM which are neither an RA nor a TA. (G) Resolution advisory (RA) : Oral and visual information provided to the flight crew to avoid a potential collision. (H) Threat : A target that has satisfied the threat detection logic and thus requires a resolution advisory.

Enables TCAS to be set to standby (STBY), automatic (AUTO), or traffic advisories only (TA ONLY) mode of operation. STBY : TCAS system is under power, but TCAS functions (intruder visualisation, Traffic Advisory mode or resolution Advisory) are not operative. AUTO : Normal operating mode of TCAS. TA only - Disables the RA mode of operation. - May be selected but should be used only to prevent unnecessary resolution advisory when operating near closely spaced parallel runways or in the cases TCAS could command Climb maneuvers resulting in an unsafe situation for the aircraft (see limitations on 2.01.05). Note : - If altitude reporting is off or not valid Mode S transponder is selected, TCAS will be in standby (RA OFF on TCAS VSI) - If appropriate, TCAS will automatically go into the TA only mode when the TCAS equipped aircraft is below the RA descent altitude and in a climb inhibit configuration. 2

TCAS test function

- The TCAS should be tested by pressing the Test" button during cockpit preparation. - Use of the self-test function in flight will inhibit TCAS operation for up to 20 seconds depending upon the number of targets being tracked. - The mode S ATC transponder will not function during some portion of the self-test sequence.

20.3 OPERATION The TCAS provides two levels of threat advisories : If the traffic gets between 20 and 48 seconds (depending on aircraft altitude) of projected Closest Point of Approach (CPA), it is then considered an intruder, and an aural and visual traffic advisory is issued. This level calls attention to a developing collision threat using the traffic advisory display and the voice message, TRAFFIC TRAFFIC". It permits mental and physical preparation for a possible maneuver to follow, and assists the pilot in achieving visual acquisition of the threat aircraft. If the intruder gets between 15 and 35 seconds (depending on aircraft altitude), of CPA, it is considered a threat and an aural and visual resolution advisory is issued. This level provides a recommanded vertical maneuver using modified TCAS VSI's and voice messages to provide adequate vertical separation from the threat aircraft, or prevents initiation of a maneuver that would place the TCAS aircraft in jeopardy. The TCAS resolution advisories are annunciated by the following voice messages, as appropriate : A

A discharge part is provided to face overpressures. CREW MEMBERS (See schematic p 9/10) The quick donning masks are stowed in readily accessible containers adjacent to each crew member seat. The mask harness inflates automatically when the mask is pulled out of the container and it can easily be donned with one hand. A mask mounted diluter demand regulator provides dilution and emergency pressure control : - In case of pressure drop, with the dilution control in the N (normal) position, diluted oxygen is provided to 2 pilots and 1 observer for a duration of 120 mn at demand flow R (10 minutes to descend from 25 000 ft to 13 000 ft and continuation of flight R between 13 000 ft and 10 000 ft for 110 minutes). - In case of smoke or noxious gas emission, xith the dilution control in the 100 % position, oxygen is provided to 2 pilots and 1 observer for a duration of 15 minutes at demand flow. CABIN ATTENDANT PORTABLE UNITS R

- One 120 l (4.25 cu ft) portable oxygen bottle is stowed under the cabin attendant seat. It permits a continuous diluted flow to cabin attendant at 13 000 ft for a duration of 30 mn. The bottle is equipped with a diluted oxygen mask. - Protective breathing equipments are located in the baggage box of the cabin. - The cabin attendant station is equiped with automatic oxygen masks boxes. PASSENGERS The main system provides passenger protection through a PAX SUPPLY valve. It controls flow to oxygen masks installed in the cabin under the hat racks and in the toilets. They are stored into mask boxes with automatic opening.

A regulator is incorporated in the mask. 1 Release clips Squeezing the red release clips unlocks the container doors. It also enables automatic inflation of mask harness, provided that pb 4 is held in TEST position or mask is extracted from container. The blinker momentarily displays a yellow cross. 2 Blinker Displays a yellow cross when there is oxygen flow, and black when there is no oxygen flow. 3 N/100% rocker Controls the selection of normal or 100% oxygen for mask delivery. It is locked in the 100% position by the UNLOCK rocker. - 100% The mask delivers 100% undiluted oxygen. - N The mask delivers diluted oxygen. 4 TEST/RESET pb Permits a test of oxygen flow without removing the mask from the container. It is springloaded to the RESET position. - TEST Provided MAIN SUPPLY pb is selected ON, oxygen flows through the mask. The blinker momentarily displays yellow cross, and the flow is audible. A lengthened hose is provided on the observer mask enabling access to the cargo with the mask. RECOVERING BOOMSET/MICRO FUNCTION WHEN THE OXYGEN MASK IS OUT OF ITS CONTAINER : Oxygen mask remaining out of its container : - Close the oxygen mask container doors. - Pres the test push button in front of the container and release it, (yellow cross disappears). The boomset/micro function is now recovered. Note : If the pilot wishes to use the oxygen mask again and recover the mask micro, R it just has to open the container doors. ATR 42 Model : 400/500

AA

30.1 DESCRIPTION (See schematic p7/8) Each control column mechanically drives the associated elevator and, through a pitch coupling mechanism, the other elevator and the opposite control column. In case of jamming, pitch control will be recovered by applying on both control columns a differential force (52daN) disengaging the pitch coupling system. The non affected channel allows the aircraft to be operated safety. System recoupling has to be performed on ground. Pitch uncoupling generates PITCH DISCONNECT" red alert. Control column travel : 11.25º up, 6.75º down. Elevators travel : 23ºup, 13º down R Elevators automatic tab travel 60 % of the pitch control course. Pitch trim is performed by offsetting both tabs neutral position. Normal trim (control column) and STBY trim (pedestal) supply appropriate part of each actuator. Each trim tab is activated by a dedicated actuator. The two actuators are synchronized by a flexible shaft. In case of pitch tabs desynchronization : - An alert is generated by the CCAS - Normal and STBY pitch trim control are inoperative - AP disconnects Trim tab travel, displayed on the pitch trim position indicator is added to the automatic tab travel. Elevators trim controlled tab travel : 9º up, 4º down Full pitch trim travel requires about 30s in normal and in STBY control. A stick pusher and a stick shaker are provided, preventing the aircraft from reaching a critical angle of attack. When the detected incidence becomes too high, the MFC sends a signal to an electric actuator which shakes the control column at stall alert thresholds. If angle of attack keeps increasing, a further threshold is reached and the MFC activates the stick pusher ; the complete pitch control linkage assembly is pushed forward. Note : There are two stick shakers, one for each control column but only one stick pusher actuator located on the captain pitch channel. In case of pitch uncoupling when the pusher triggering angle of attack is reached, only the captain control column is pushed forward.

50.1 DESCRIPTION The aircraft is equipped with : - a Cockpit Voice Recorder, CVR, and - a Digital Flight Data Recorder, DFDR. The recorders are automatically energized as soon as the aircraft is on its own electrical supply and are switched OFF automatically TeN minutes after engines cut. When the aircraft is on external power, recorders are OFF until one engine is started. They can be energized by selecting ON the RCDR pushbutton, and deenergized by pushing the RESET pushbutton. Each recorder is equipped with an underwater acoustic beacon which is used to locate the recorder in the event of an aircraft accident over the sea. The beacons actuate immediately after immersion. They should transmit a signal on 37.5 kHz for 30 days. The detection range is 3.5 km (4,000 yards). CVR All crew communications transmitted through the RCAU are recorded. In addition, a CVR microphone, located below the overhead panel, acquires cockpit conversation and aural alerts for recording. Cabin crew announcements are also recorded. Only the last 30 minutes (or 120 minutes, depending on version) are retained. All recording may be erased by pressing ERASE pushbutton provided the aircraft is on ground and the parking break is set. DFDR Various aircraft parameters are sent to a Flight Data Acquisition Unit (FDAU) which converts them into digital data. The data are recorded by the DFDR which stores them on a magnetic tape. The 25 last hours of flight are retained.

ENGINE FEED (See schematic p 13/14) In normal conditions, each engine is supplied from its associated wing tank. Fuel flow/fuel used ind. allow the crew to monitor fuel consumption for each engine. Each tank is fitted with a 200 l feeder compartment always full of fuel protecting the engine feed system against negative or lateral load factors. In the feeder compartment, an electrical pump and a jet pump are installed. The jet pump is activated by HP fuel from the engine HMU and is controlled by a motive flow valve. Note : Each electrical pump is able to supply one engine in the whole flight envelope. In normal operation, the electrical pump is only used to start the engine. After start , jet pump takes over automatically. R If jet pump pressure drops below 350 mbar (5PSI), the electrical pump is automatically activated to supply the engine. A crossfeed valve, controlled by an electrically operated actuator, allows both engines to be fed from one side or one engine to be fed by either tank, allowing control of an unbalance situation. When the crossfeed valve is open, a blue “FUEL X FEED” light comes on memo panel. In this case, the two electrical pumps are automatically actuated. It’s possible to use only one fuel tank by switching off the opposite pump pb. At the fuel outlet of each tank a fuel LP valve, controlled by the associated fire handle, is installed.

TERRAIN CLEARANCE FLOOR The Terrain Clearance Floor (TCF) mode creates an increasing terrain clearance envelope around the airport runway directly related to the distance from the runway. The alert is based on current aircraft location, nearest runway center point position and radio altitude. TCF is activated during takeoff, cruise and final approach and complement existing Mode 4 by providing an alert based on insufficient terrain clearance even when in landing configuration. A Runway Field Clearance Floor (RFCF) alert is also provided for runways that are located on top of a hill. This alert is similar to the TCF alert but is based on height above runway. The aural message Too Low Terrain" will occur once at the initial TCF envelope penetration and one time thereafter for each 20% degradation in radio altitude. At the same time GPWS" red alert lamp are illuminated and remain on until the alert envelope is exited.

TERRAIN AND OBSTACLE AWARENESS This function uses aircraft geographic position provided by an aircraft GPS or an optional internal GPS card, aircraft altitude and a worldwide terrain database to predict potential conflicts between the aircraft flight path and the terrain, and to provide aural alert and graphic displays of the conflicting terrain. S Terrain / Obstacle Alerting Caution and Warning envelopes below and ahead of the aircraft path are computed as a function of airspeed and flight path angle. It the aircraft penetrates the Caution envelope boundary, an aural message TERRAIN AHEAD. TERRAIN AHEAD" or OBSTACLE AHEAD, OBSTACLE AHEAD" (for obstacle detection) is generated with the red GPWS" lights illuminated on each instrument panel. Simultaneously, terrain areas, which conflict with the Caution criteria, are shown in solid yellow on the Terrain Display. If the aircraft penetrates the Warning envelope boundary, an aural message TERRAIN AHEAD, PULL UP" or OBSTACLE AHEAD, PULL UP" (for obstacle detection) is generated with the red GPWS" lights illuminated on each instrument panel. Simultaneously, terrain areas, which conflict with the Caution criteria, are shown in solid red on the Terrain Display. S Terrain /Obstacle Display The terrain data can be displayed on the Electronic Flight Instrument System (EFIS). When the Terrain Display is present, it replaces the Weather Radar display and can be available to the flight crew at any time. A discrete pop-up signal provided by EGPWS is used to automatically display on EFIS the detected threatening terrain or obstacle with an auto-range of 10Nm,whatever is the previous information displayed. The local terrain forward of the aircraft is depicted as variable density dot patterns in green, yellow or red. The density and color being a function of how close the terrain is relative to aircraft altitude. Terrain Alerts are depicted by painting the threatening terrain or obstacle as solid yellow or red.

60.1 DESCRIPTION (See schematic p11/12) Using information provided by a constellation of 24 satellites (the HT 1000 is able to track up to 12 satellites at a time), GNSS is an automatic tridimensional (latitude, longitude, altitude) location and navigation means. It also uses data recorded in a data base. The data base is stored in the NPU and is updated every 28 days on the ground using a specific data loader. The effective date periods are displayed on the MCDU IDENT page. The navigation is normally performed using the GPS sensor (GPS mode). In the R case of the GPS position becomes unavailable, the HT1000 reverts to DME-- DME mode R (if installed) and radio coverage allows it. If not, the dead reckoning mode (DR) R is used as a back-- up using true airspeed, heading and the last computed wind data.

FUNCTIONS HT 1000 is capable of performing all the functions associated with the great circle navigation. It mainly allows to perform: - ”Direct To” navigation - Flight plan navigation - Navigation to nearest airport (or nearest VOR, NDB...) - Vertical navigation (non coupled to auto pilot) - Non precision approach To know all the functions available, refer to the table of contents of the HT 1000 pilot’s guide.

20.3 LUBRICATION SYSTEM


Synthetic oil specification MIL-L-23699. A single oil system serves the turbo machinery, the reduction gear box and the propeller pitch change system. - Oil tank Oil is contained in a 14.4 L tank 1 . A filter cap is provided on the tank. Quantity indication is checked by sight glass (or by a dipstick) on the side of the tank. - Pressure system A gear pump 2 driven by the accessory gear box supplies oil through an air cooler 3 mounted in the nacelle and a filter 4 both fitted with by-passes in case of clogging. RGB oil is also cooled in a fuel heater, 5 as well as in the FCOC 6 . An oil temperature sensor is provided. Oil pressure is controlled by a regulating valve 7 . A low temp. valve 8 is provided to eliminate damaging pressures surges on cold starts. A pressure transducer 9 and a low pressure switch 10 are installed. - Scavenge system Scavenging is blown down or gravity drained except for N° 6 and 7 bearing cavity and the reduction gear box, on which gear pumps are used. 20.4 IGNITION SYSTEM Each engine is equipped with a high energy ignition system. It consists of two engine mounted ignition exciters (A and B) powered by the DC ESS BUS and two spark R igniters, one for each ignition exciter. Ignition cycle includes two phases. During 25 sec, R the intensity is 5 to 6 sparks/sec and then, the intensity becomes 1 spark/sec. The engine ignition system provides ignition for : - On ground starting using exciter A, exciter B, or exciters A + B (according to ENG START rotary selector position). Note : Using exciter A or exciter B may allow to detect an hidden failure. - In flight starting using exciters A + B regardless of start selection. In addition, for each engine, in case of NH drop below 60 %, exciters A + B are automatically activated. This action is inhibited if : - NH drops below 30 %, or - EEC is deselected, or - CL is set on feather or fuel S/O position, or - On the failed engine in case of ATPCS sequence. Note : When EEC is deselected, exciters A + B can manually be activated, using the MAN IGN guarded push-button. ATR 42 Model : 500

ENGINE POWER CONTROL LAWS R

TOP LAW (EEC ON) This is a TQ (PLA) control law, ensuring a constant power. It is backed-up by an NH (PLA) law which becomes active : - At low power (authority of engine torque control is gradually reduced to be cancelled out at FI), - In case of engine torque control failure, - In Hotel mode. 1

According to the rating selected on the PWR MGT rotary selector, with the PL at a set point, the EEC commands a determined engine power and therefore a torque value (for a given propeller speed). Thus, the torque which is the engine control parameter, is controlled (with PLA constant) in all ambient conditions.

Note : Nothing happens on the affected engine for 2.15 seconds, but uptrim is energized on the remaining engine. This feature enables to perform an acceleration stop without having autofeather in order to benefit from some reversing action on the failed engine. In this case, the throttle reduction occuring within 2.15 seconds period automatically disarms the mode. Once the mode has been triggered, its cancellation can only result from either : - PWR MGT other than TO, or - ATPCS Pb set to OFF, or - both PL retarded. CAUTION : If the engine is restarted, IT WILL BE NECESSARY TO SELECT PWR MGT to MCT position after relight in order to be able to UNFEATHER the propeller.

TCAS operation is approved for use in VFR meteorological conditions (VMC) and IFR meteorological conditions (IMC).

2--

The pilot must not initiate evasive maneuvers using information from the traffic display only or from a traffic advisory (TCAS TA) only. These displays and advisories are intended only for assistance in visually locating the traffic and lack the resolution necessary for use in evasive maneuvering.

3--

Compliance with TCAS resolution advisory is required unless the pilot considers it unsafe to do so. However, maneuvers which are in the opposite direction of the resolution advisory (TCAS RA) are extremely hazardous and are prohibited unless it is visually determined they are the only means to assure safe separation. CAUTION : Once a non crossing RA has been issued the vertical speed should be accurately adjusted to comply with the RA, in order to avoid negating the effectiveness of a co-- ordinated maneuvre by the intruder. WARNING : Non compliance with a crossing RA by one airplane may result in reduced vertical separation. Therefore, safe horizontal separation must also be assured by visual means.

Evasive maneuvring should be made with the autopilot disengaged, and limited to the minimum required to comply with the RA. The pilot must promptly return to the previous ATC clearance when the TCAS “CLEAR OF CONFLICT” voice message is announced.

Because of the limited number of inputs to TCAS for determination of aircraft performance inhibits, there are instances where inhibiting RAs would be appropriate, however it is not possible to do so. In these cases, TCAS may command maneuvers which may significantly reduce stall margins or result in stall warning. Conditions where this may occur include operations with a bank angle (wings level is assumed), weight, altitude and temperature combinations outside those noted below, leaving aircraft in landing configuration during climb RA on approach, engine out operations, and abnormal configurations such as landing gear not retracted or stick pusher/shaker failure. The table below entitled “Flight Envelope in which climb resolution advisory can be accomplished without stick pusher/shaker activation” outlines the parameters used in the development of the performance inhibits. This table does not consider worst turboprop flight conditions especially operations using minimum operating airspeeds as are sometimes required (e.g. obstacle clearance, ATC constraints). In all cases, stall warning must be given precedence over climb RA commands. NOTE :

TCAS is viewed as a supplement to the pilot who, with the aid of the ATC system, has the primary responsibility for avoiding mid-- air collisions.

WARNING : Priority must be granted to increasing airspeed when reaching stall warning even when this requires deviation from an RA command issued by the TCAS.

PITCH : Both elevators are connected through a pitch uncoupling device, in order to leave sufficient controllability in case of mechanical jamming of one control surface. Activation of this device : - Requires heavy forces (52 daN/114 Ibs) to be applied to the control columns, which minimizes the risk of untimely disconnection. - Indicated to the crew through the red warning « PITCH DISCONNECT ». - Allows the flight to be safely achieved : refer to PROCEDURES FOLLOWING FAILURES. Note 1 : WHEN PITCH DISCONNECT takes place WITHOUT REAL JAMMING, speed has to be limited to 180 kt and bank angle to 30° until flaps extension to avoid overstressing the stabilizer. Note 2 : The TWO sticks must be held once the aircraft is landed. Once disconnected both elevators can be reconnected by applying the following procedure : BOTH ELEVATORS RECONNECTION ON GROUND Conditions : R - Aircraft on ground and electrically powered. - Both elevators disconnected. - Red PITCH DISCONNECT alarm illuminated steady on CAP.

Aileron spring tabs Flight controls are connected to the ailerons through the spring tabs, therefore, maintaining the flight controls to neutral on the ground would not prevent the ailerons from oscillating in case of heavy tail wind (> 30 kt). Therefore, in heavy wind conditions it is recommanded : - to disengage the gust lock only when necessary before take off. - after landing, to engage the gust lock before a turn that would expose the aircraft to a tail wind component. If aileron lock is not available, it is easier to maintain the ailerons fully deflected.

In order to avoid exceeding structural loads on the rudder and vertical stabilizer, the following recommendations must be observed. 1) THE RUDDER IS DESIGNED TO CONTROL THE AIRCRAFT, IN THE FOLLOWING CIRCUMSTANCIES: a) In normal operations, for directional control -During the takeoff roll, when on ground, especially in crosswind condition. -During landing flare with crosswind, for decrab maneuver. -During the landing roll, when on ground. -The rudder may be used as deemed necessary, for turn coordination to prevent excessive sideslip. b) To counteract thrust asymmetry Full rudder authority can be used to compensate for the yawing moment of asymmetric thrust. Note : at high speed (i.e. flaps up), thrust asymmetry (i.e. due to an engine failure) has relatively small effect on lateral control of the aircraft. The amount of rudder required to counter an engine failure and center the sideslip is small. c) In some other abnormal situations The rudder may also be used in some abnormal situations such as: -Runaway rudder trim. The rudder pedals may be used to return the rudder to neutral. -Aileron jam. The rudder may be used to smoothly control the roll. -Landing gear unsafe indication (gear not downlocked). When a main landing gear is not downlocked, the rudder may be used to establish sideslip in an attempt to downlock the landing gear by aerodynamic side forces. -Landing with landing gear not downlocked. The rudder can be used for directional control on ground. In all these normal or abnormal circumstances, proper rudder maneuvers will not affect the aircraft's structural integrity. 2) RUDDER SHOULD NOT BE USED: -To induce roll, except in the previous case( Aileron jam) or -To counter roll, induced by any type of turbulence. Whatever the airborne flight condition may be, aggressive, full or nearly full, opposite rudder inputs must not be applied. Such inputs can lead to loads higher than the limit, or possibly the ultimate loads and can result in structural damage or failure. Note : Rudder reversals must never be incorporated into airline policy, including so-called aircraft defensive maneuvers" to disable or incapacitate hijackers. As far as dutch roll is concerned, yaw damper action (if selected) or RCU (Releasable Centering Unit) are sufficient to adequately dampen dutch roll oscillations. The rudder should not be used to complement the yaw damper action.

FUEL QUANTITY INDICATIONS IN FLIGHT Accurate readings require aircraft levelled without side slip and pitch attitude close to zero degree. ON GROUND Accurate readings should be made with aircraft static (not taxiing) and fuel pumps running for more than 4 minutes. This procedure should be applied each time a comparative reading before and after flight is intended with correlation to fuel used. COMMENTS - Fuel quantity indications are affected by excessive longitudinal and lateral attitudes and accelerations. - Fuel quantity indications are affected by the level of fuel in the feed tank. With pumps running, the feed tanks are filled within a few minutes. This is the normal flight case.

R This chapter is divided in four parts : - Icing, - Cold weather operations, - Operations in wind conditions R - Volcanic Ash encounter ICING I - GENERAL Icing conditions are defined as follows : " Atmospheric icing conditions. Atmospheric icing conditions exist when OAT on ground and take-- off is at or below 5°C or when TAT in flight is at or below 7°C and visible moisture in the air in any form is present (such as clouds, fog with visibility of one mile or less, rain, snow sleet and ice cristals). " Ground icing conditions Ground icing conditions exist when the OAT is at or below 5°C when operating on ramps, taxiways and runways where surface snow, standing water or slush is present. " Regulatory requirements Certification requirements defined in JAR/FAR 25 appendix C consider droplet sizes up to 50 microns in diameter. No aircraft is certified for flight in conditions with droplets larger than this diameter. However, dedicated flight tests have linked unique ice accretion patterns to conditions of droplet sizes up to 400 microns. Procedures have been defined in case of inadvertent encounter of severe icing. " Organization of this subchapter It will address the following areas : F

Operations within the certified envelope.

II - OPERATIONS WITHIN THE CERTIFIED ICING ENVELOPE PREAMBULE Icing conditions should never be assessed with complacy. Although the aircraft is adequately protected for most of the encountered cases, any severe icing exposure should be minimized by a correct evaluation and proper avoiding actions. A) GENERAL Operations in atmospheric icing conditions require SPECIAL ATTENTION since ice accretion on airframe and propellers SIGNIFICANTLY modifies their aerodynamic characteristics. The primarily considerations are as follows : a - Even small quantities of ice accretions, which may be difficult to detect visually, may be sufficient to affect the aerodynamic efficiency of an airfoil. For this reason, ALL ANTI ICING PROCEDURES and SPEED LIMITATIONS MUST BE COMPLIED WITH as soon as and as long as ICING CONDITIONS are met and even before ice accretion actually takes place. b - Main effects of ice accretion on airfoils are : S Maximum achievable LIFT is reduced. S For a given angle of attackm LESS LIFT and MORE DRAG are generated. In order to maintain a SAFE MARGIN AGAINST STALL, which will occur at a higher speed when ice accretion spoils the airfoil : - the stall warning threshold must be reset to a lower value of angle of attack, - the stick pusher activation threshold is lowered accordingly. These lowered thresholds are effective when switching horns anti icing ON and illuminating the ICING AOA green caption. R R

THE LOWER AOA OF STALL WARNING AND STICK PUSHER ACTIVATION THRESHOLD DEFINED FOR ICING REMAIN ACTIVE AS LONG AS THE ICING AOA" CAPTION IS ILLUMINATED. - Accordingly, the minimum maneuver/operating speeds defined for normal (no icing) conditions (see FCOM 2.02.01) MUST BE INCREASED. These new minimum speeds are called MINIMUM ICING SPEEDS". They are defined further in paragraph B.

The ice detector may not detect certain ice accretion form (see FCOM 1.13.20). 3.If a noticeable performance decrease and (or) significant vibrations occur due to propeller residual icing then, in order to improve the deicing of the blades, it is recommended : F To check that the MODE SEL is AUTO, or that the MAN mode is selected in accordance with SAT. F To set CLs on 100 OVRD for continuous periods of not less than 5 minutes in order to benefit from an increased centrifugal effect. 4.If ice accretion is seen by the detector with HORNS ANTI ICING and/or AIRFRAME DE ICING still OFF, the ICING light will flash until corrective actions are taken. 5.Engines de-icing must be selected ON prior to airframe de-icing to take benefit of an immediate engines de-icing. If not, engines de-icing will be effective 60 or 240 seconds later depending on MOD SEL selection.

ADVERSE WEATHER 3) Mixed icing condition

Mixed icing condition may be encountered in the range of temperatures - 10°C/0°C. It is basically an unstable condition, it is extremely temperature dependent and it may change quite rapidly. This condition may surpass the ice protection capabilities because the aggregate of impinging ice crystal/snow and water droplet can adhere rapidly to the airplane surpassing the system capabilities to shed ice, causing significant reduction in airplane performance as in case of system failure. C) CONSEQUENCES OF SEVERE ICE ACCRETION The consequences of severe ice accretions are ice location dependent. If the pollution extension occurs on the lower surface of the wing, it increases the drag and the airplane speed decreases. It may lead to stall if no action is taken to recover a correct speed. If the pollution occurs first on the upper part of the wing, the drag is not affected noticeably but controllability anomalies may be encountered. Severe roll anomalies may be encountered with flaps 15" accretions flown with flaps 0 setting. It should be emphasized that it is not the flaps 15 configuration itself that is detrimental, but the low angle of attack that may result from such a setting, especially close to VFE. This low or negative AOA increases the wing upper side exposure to large droplet impingement. This is why holding with any flaps extended is prohibited in icing conditions (except for single engine operations). R

R

- During flight, severe icing conditions that exceed those for which the airplane is certificated shall be determined by the following : Severe icing is characterized by ice covering all or a substantial part of the unheated portion of either side window, Note : This cue is visible after a very short exposure (about 30 seconds). and / or Unexpected decrease in speed or rate of climb, and / or The following secondary indications : . Water splashing and streaming on the windshield. . Unusually extensive ice accreted on the airframe in areas not normally observed to collect ice. . Accumulation of ice on the lower surface of the wing aft of the protected areas. . Accumulation of ice on the propeller spinner farther aft than normally observed. - The following weather conditions may be conducive to severe in-flight icing : . Visible rain at temperatures close to 0°C ambient air temperature (SAT). . Droplets that splash or splatter on impact at temperatures close to 0°C ambient air temperature (SAT). - The occurence of rain when SAT is below freezing temperature should always trigger the alertness of the crew. EXIT THE SEVERE ICING ENVIRONMENT There are no regulatory requirements to certify an aircraft beyond JAR/FAR 25 Appendix C. However, in case of inadvertent encounter with such conditions severe icing procedure must be applied (refer to 2.04.05).

IV - GOOD OPERATING PRACTICES Aircraft certification requirements describe the icing conditions likely to be encountered in commercial aviation. However, as demonstrated by experience, icing remains one of the major causes of incidents and accidents, and good airmanship prohibit any complacency in this area. The following basic rules should therefore be applied : " Know as much about your operating environment as you can. Carefully review weather packages for Pilot reports of icing conditions, tops reports, temperatures aloft forecasts and forecasts of icing, freezing drizzle and freezing rain. Monitor both Total Air Temperature and Static Air Temperature during climb and while en route. Use the weather radar. Areas of precipitation which will paint on the radar will be of sufficient droplet size to produce freezing rain when encountered in freezing temperatures or on a cold soaked aircraft. " Marginal freezing temperatures and icing conditions should create a heightened state of awareness. Remember, severe ice can still be incurred at temperatures down to approximately - 18° C, at high altitude. R " Be alert to severe icing cues defined pages 12/13. R " When severe icing is encountered, take appropriate steps to leave the conditions. Since these unique conditions are usually small in area and associated with very specific temperatures conditions, a change in altitude of just a couple thousand feet may place you in a totally different environment. " Make reports to ATC and Company. There is no better operational tool available today than first hand reports of these conditions. Remember that because these are localized areas and extremely temperature dependent, another aircraft passing through the same area at a different airspeed may experience different conditions. For example, a laboratory test showed for a specific, yet normal condition, rime ice up to about 150 kt, mixed ice as speed was increased to about 200 kt, glaze ice between 200 and 360 kt, and no accretion above 360 kt. Note : Reporting of icing conditions as defined in the FAA's Airman's information Manual (AIM) : Trace : Ice becomes perceptible. Rate of accumulation is slightly greater than the rate of sublimation. It is not hazardous even though deicing/anti-icing equipment is not utilized unless encountered for an extended period of time (over 1 hour). Light : The rate of accumulation may create a problem if flight is prolonged in this environment (over 1 hour). Occasional use of de-ice/anti-icing equipment removes/prevents accumulation. It does not present a problem if the deicing/anti-icing equipement is used. Moderate : The rate of accumulation is such that even short encounters become potentially hazardous and use of deicing/anti-icing equipment or flight diversion is necessary. Severe : The rate of accumulation is such that deicing/anti-icing equipment fails to reduce or control the hazard. Immediate flight diversion is necessary.

CAUTION : Wing, tailplane, vertical and horizontal stabilizers, all control surfaces and flaps should be clear of snow, frost and ice before take off. PARTICULAR CASE : limited frost accretion on lower wing surfaces due to cold fuel remaining and high ambient humidity. As stated in the operational requirements, no person may take off an aircraft when frost snow or ice is adhering to the wing, control surfaces or propeller of the aircraft. FROST : frost is a light, powdery, crystalline ice which forms on the exposed surfaces of a parked aircraft when the temperature of the exposed surfaces is below freezing (while the free air temperature may be above freezing). Frost degrades the airfoil aerodynamic characteristics. However, should the take off be conducted with frost adhering to the lower surface of the wing, check the following : - The frost is located on the lower surface of the wing only. - Frost thickness is limited to 2 mm. - A visual check of the leading edge, upper surface of the wing, control surfaces and propellers is performed to make certain that those surfaces are totally cleared of ice. - Performance decrement and procedures defined for take off in atmospheric icing conditions are applied. " DE ICING / ANTI ICING PROCEDURE R - External de-- /anti-- icing will be performed as close as possible from take-- off time in order not to exceed the hold over time. Type 1 (low viscosity) or type 2/4 (high viscosity) fluids are used for these operations. The type 2/4 fluids are used for their anti icing qualities. As airflow increases the fluid is spread through the elevator gap and over the lower surface of the elevator. Depending on the brand of the fluid and the OAT, this phenomenon may temporarily change the trim characteristics of the elevator by partially obstructing the elevator gap. This may lead to a considerable increase in control forces necessary to rotate. This effect is most pronounced when center of gravity is forward. R - To ensure the best possible tailplane de-- /anti-- icing, all along the fluid spraying, the R pitchwheel must be firmly maintained on the forward stop together with the aileron gust R lock engaged. R - De-- /anti-- icing may be performed in Hotel mode provided BLEEDS are selected OFF. If a de icing gantry is used, both engines must be shut down. For manual propeller de icing, the engines must be shut down and air intake blanked or precaution taken not to have de icing fluid in the air intake. No propeller blade should be located at 6 o’clock position during this procedure.

" TAXIING - The standard single engine TAXI procedure may still be used provided the friction coefficient remains at or above 0.3 (braking action medium, snowtam code 3) and nose wheel steering is not used with too large deflections. Note : If the OAT is very low, it may be necessary any way to start up engine 1 early enough to get the necessary oil warm up time (refer to Note (3) above). - For taxiing with very low friction coefficients (icy taxiways, slush,) it is recommended to use both engines, limit nose wheel travel and use with differential power as necessary. SPECIAL CASE If contaminant layer is significant enough to possibly accumulate in the brake area during ground operation, brakes disks may join due to icing during the flight, leading to possible tyres damages at subsequent landing. The following special procedure should be applied during taxi before and as close as possible to take off. Set 18% Torque on each engine and keep taxi speed down to a "man pace" during 30 seconds using normal brakes with minimum use of nose wheel steering to ensure a symmetrical warming up of the brakes.

" TAKE OFF - Standard take off procedure has to be used with the following additions : .S If runway is contaminated (ice, snow, slush), use the relevant performance penalties definied in the performance section 3.03. .S Use of reverse on contaminated runways has to be limited at very low speeds to avoid contaminant projections at the level of cockpit windshield which may reduce visibility to zero (snow, slush). .S In atmospheric icing conditions, refer to appropriate speeds and performance penalties and add the following : - with very cold OAT, delay start of take off roll until oil temperature is at least 45_C (this is necessary to guarantee inlet splitter de icing capability). R

R

After the ground de icing/anti icing procedure, using type II/IV fluids, higher than normal stick forces may be encountered. These control input forces may be more than twice the normal take off force. This should not be interpreted as a `pitch jam` leading to an unnecessary abort decision above V1. Although not systematic, this phenomenon should be anticipated and discussed during pre-take off briefing each time de icing/anti icing procedures are performed. These increased pitch forces are strictly limited to the rotation phase and disappear after take off.

R R R

In very exceptional circumstances, because of increased rotation forces, the pilot can consider that take off is impossible and consequently initiate an aborted take off . The consequences of this decision are catered for by a specific performance penalty (Refer to AFM SUPPLEMEMTS chapter).

R

AFTER V1, BE TAKE OFF MINDED " BEFORE LANDING If take-off has been performed on a slush contaminated runway, this slush may seize the brakes during cruise. To prevent tire damage at touch down : in final approach, after the selection of GEAR DOWN, select the ANTISKID to OFF, then pump the brakes at least 5 times and then reselect the ANTISKID to ON. " LANDING Same restrictions on reverse than for accelerate stop. Apply relevant performance restrictions. " PARKING When OAT is below - 5_C / 23_F, particularly in wet conditions, avoid leaving the aircraft with parking brake engaged and use chocks instead whenever possible. ATR 42 Model : 400/500

Windshear This phenomenon may be defined as a notable change in wind direction and/or speed over a short distance. Windshear can be encountered in the vicinity of thunderstorms, into rain showers (even without thunderstorms), during a frontal passage or on airports situated near large areas of water (sea breeze fronts). Severe windshear encountered above 1000 feet, whilst unpleasant, can generally be negociated safely. However if it is encountered below 500 feet on take off or approach/landing it is potentially dangerous. As far as possible this phenomenon must be avoided. Procedure at take off : • Delay the take off. If a low level windshear is reported calculate VR, V2 at the maximum take off weight available for the day. • When clear of obstacles accelerate as much as possible and clean up the aircraft. • Climb at the normal climb speed. Procedure during an approach : If a windshear is encountered, • Initiate a normal go around procedure with 10° pitch . • When positively climbing at a safe altitude, retract the gear and complete the normal go around procedure. CAUTION :

The positive rate of climb must be verified on at least two instruments.

COMMENTS :

1. Leaving the gear down until the climb is established will allow to absorb some energy on impact, should the microburst exceed the aircraft capability to climb. 2. Ten degrees pitch attitude is the best compromise to ensure a climbing path together with an acceptable maximum AOA.

VOLCANIC ASH ENCOUNTER 1- VOLCANIC ASH DESCRIPTION Volcanic ash is, essentially, extremely fine particles of glass shards and pulverized rock, the composition of which reflects the composition of the magma inside the volcano. It is composed predominantly of siliceous materials (> 50%) that are both very hard and very abrasive. The melting point of glassy silicates is around 1100_C that is close to the operating temperature of the engine at cruise thrust. The ash is accompanied by gaseous solutions of sulphur dioxide (sulphuric acid) and chlorine (hydrochloric acid). 2- AVOIDANCE Flight operations in volcanic ash are extremely hazardous and must be avoided. Flights in areas of known volcanic activity must be avoided. When a flight is planned into an area with known potential for volcanic activity: - All NOTAMS and air traffic advisories have to be checked for current status of volcanic activity. - The planned route has to well avoid the area of volcanic activity. - If possible, stay upwind of volcanic ash. The first two or three days following an explosive eruption are especially critical because high concentration of gas with hazardous concentration could be encountered at cruise levels some considerable distance from the volcano. Beyond three days, it is assume that if the ash is still visible by eye or from a satellite data, it still presents a hazard to aircraft. 3- DETECTION Volcanic ash cloud does not produce ”return” or ”echoes” on the airborne weather radar. Volcanic ash may be difficult to detect visually, especially at night or on instrumental meteorological conditions. However, the following have been reported by flight crew: - Acrid odor, similar to electrical smell, burned dust or sulfur. - Smoke or dust appearing in the cabin and cockpit, leaving a coating on cabin and cockpit surfaces. - Multiple engine malfunctions, such as stall, increase ITT, flameout. - Airspeed fluctuating erratically. - At night, static electric discharges (St. Elmo’s fire) visible around the cockpit windshields. - At night, landing lights cast sharp, distinct shadows on the volcanic ash clouds as opposed to the normally fuzzy, indistinct shadows cast on water / ice clouds. 4- EFFECTS ON POWERPLANT The melting point of volcanic ash is close to the operating temperature of the engine at cruise power. This can cause serious damage in hot section of the engine that could result in engine thrust loss and possible flame out. (.../...) ATR 42 Model : 400/500

2.02.08


001 DEC 09

AA

4- EFFECTS ON POWERPLANT (CONT’D) Pilots are therefore asked to reduce engine power settings to flight idle when possible to lower the engine operating temperature below the melting point of volcanic ash. The volcanic ash, being abrasive, also damage engine components causing loss of engine thrust. The erosion also results in a decrease in the engine stall margin. Although this abrasion effect takes longer than the melting fusion of volcanic ash to shut down the engine, the abrasion damage is permanent and irreversible. Reduction of engine thrust to idle slows the rate of erosion by the compressor blades but can not eliminate it entirely while the engine is still ingesting air contaminated by volcanic ash. Propeller blades may also be degraded by erosion inducing loss of traction efficiency. Oil cooler efficiency may also be decreased either due to excessive erosion of the cooler or due to blockage of the air intake by ashes. 5 - EFFECTS ON THE AIRFRAME AND EQUIPMENT Volcanic ash abrades cockpit windows, airframe and flight surfaces. Any parts protruding from airframe such as antennas, probes, ice detectors can be damaged and may be rendered inoperable. - The abrasion of the cockpit window reduces the pilot’s forward visibility. This can lead to serious problems during landing phase. - The abrasion damage of the wing or horizontal stabilizer leading edges can either prevent the correct operation of the de-- icing boots or even detached parts of the boots with subsequent drag increase. - The abrasion damage of the landing lights can significantly reduce landing light effectiveness. - Damage to the antennas can lead to a complete loss of HF communications and a degradation of VHF communications. - Damage to the various sensors can seriously degrade the information available to the pilot through the instrument. Volcanic ash can obstruct probes and penetrate into air conditioning and equipment cooling system. It can contaminates electrical and avionic units, fuel and hydraulic system and smoke detection system. - Pitot probe can be blocked by volcanic ash resulting in unreliable airspeed indications or complete loss of airspeed indication in the cockpit. Volcanic ash columns are highly charged electrically. The static charge on the aircraft creates a ”cocoon” effect which may cause a temporary defection, or even complete loss of VHF or HF communication with ground stations. (.../...)

TAKE OFF : USE OF BLEED VALVES The aircraft is fitted with an automatic bleed valve closing in case of engine failure at take off. The closing signal is given by MFC's when uptrim is triggered. BLEED FAULT light also illuminates on the operative engine. Engine bleed valves may be routinely selected ON (NORM FLOW) for take off. However, performance decrement has to be considered for the ground phase. This decrement is given in chapter 3.03 and may be computed by the FOS. POWER SETTING AT TAKE OFF Engine control normally uses temperature, altitude and speed data from the selected ADC but reverts to its own sensors in case of detected failure or significant offset. TAT/SAT information are valid only whne the engine (propeller unfeathered) corresponding to the selected ADC is running. RTO torques must be computing using altitude and temperature information independent from aircraft sources and compared to values displayed by torque bugs. Take off power is routinely obtained by setting the power levers and the condition levers into the notches.

REVERSE PHASES NP is the parameter to be monitored during reverse phases. (NP is the only regulated parameter in these phases) OPERATIONS OUT OF THE NOTCH When PL are retarded, during descent and approach, trim efficiency is reduced (reference point being notch), and cannot correct built-- in discrepencies between engines and their associated controls. Tolerances due to PL rigging cannot be compensated in that area. TQ split up to 8% (8 counts) can be evidenced between engines in stabilised conditions. This is built-- in and results from requirement of TQ accuracy in notch, which is the power setting used for about 90% of flight time. TQ differences are allowable and can be eventually compensated manually by crew with PL adjustment.

TAKE OFF AND LANDING RUNS - Proper crew coordination is required in order to hold the control column at all times and prevent excessive elevator or aileron deflections due to wind and/or reversed air flow from propellers. The control column is initially held : F F

in pitch : fully nose down, then slowly relaxed as speed increases. in roll : neutral or deflected TOWARD the wind in case of crosswind component, as appropriate to maintain wings essentially level. Note : Excessive aileron deflections should be avoided as they affect directional control.

- For take-- off, use of nose wheel steering guidance is only recommended for the very first portion of the take-- off run as rudder becomes very rapidly efficient when airspeed increases (~ 40 Kts) and aircraft exhibits a natural tendency to go straight. - Action on NWS should be smooth and progressive, particularly as ground speed increases. - Rudder must not be cycled during take-- off, particularly the first portion where NWS is used : combination of unnecessary rudder cycling (with an increasingly efficient rudder) and NWS control would then lead to uncomfortable oscillations. - Rolling take-- off technique. In order not to increase the take-- off distances, power must be set quickly during the last phase of the line up turn. - For landing or aborted take off, control column holding must be transfered to the co-- pilot when the captain takes the NWS. If reverse is used, at low speeds and with high power, the reversed air flow may shake violently the flight controls, particularly with no crosswind : the control column must be held very firmly and/or, below 30 kts, the GUST LOCK may be engaged. R

Narrow Runways : When the aircraft is operated on a narrow runway (width < 30 m (98 ft)), whoever is the PF (CM1 or CM2), the CM1 should be ready to use Nose Wheel Steering as soon as the nose wheel is on the ground. If reverse is used, at low speeds and with high power, the reversed air flow may shake violently the flight controls, particularly with no crosswind : the control column must be held very firmly and/or, below 30 kts, the GUST LOCK may be engaged.

FLIGHT CHARACTERISTICS STALLS STALL WITHOUT ICE ACCRETION

In all configurations, when approaching the stall, the aircraft does not exhibit any noticeable change in characteristics of flight : control effectiveness and stability remains good and there is no significant buffet down to CL max ; this is the reason why both the stall alert (audio cricket" and shaker) and stall identification (stick pusher) are artificial" devices based on angle of attack measurement. Recovery of stall approaches should normally be started as soon as stall alert is perceived : a gentle pilot push (together with power increase if applicable) will then allow instant recovery. If the stall penetration attempt is maintained after stall alert has been activated, the STICK PUSHER may be activated : this is clearly unmistakable as the control column is suddenly and abruptly pushed forward, which in itself initiates recovery. Note : The pushing action" is equivalent to 40daN/88 lbs applied in 0.1 second and it lasts as long as angle of attack exceeds the critical value. CAUTION : Stall training excercices without stick pusher are prohibited. STALL WITH ICE ACCRETION Even with airframe de-icers used according to procedure (i.e. as soon as and as long as ice accretion develops on airframe), the leading edges cannot be completely cleared of ice accretion because of existence of unprotected" elements on the leading edges and continued accretion between two consecutive boots cycles. This residual ice on leading edges changes noticeably the characteristics of flight BELOW the minimum operating speeds defined for ice accretion, as follows : - Control effectiveness remains good, but forces to manoeuver in roll and to a lesser degree in pitch, may increase somewhat. - Above the reduced angle of attack : . An aerodynamic buffeting may be felt which will increase with the amount of ice accumulated and angle of attack increase. . Stability may be slightly affected in roll, but stick pusher should prevent angle of attack increase before wing rocking tend to develop (Refer to FCOM 1.02.30 for stall alarm threshold definition).

R R

Recovery of stall in such conditions must be started as soon as stall warning is activated or buffeting and/or beginning of lateral instability and/or sudden roll off is perceived. Recovery will be best accomplished by : - A pilot push on the wheel as necessary to regain control. - Selection of flaps 15. - Increase in power, up to MCT if needed.

APPROACH - The deceleration capabilities of the aircraft provide a good operational advantage which should be used extensively : decelerated approaches reduce noise, minimize time and fuel burn and allow better integration in big airports. This is why they have been described as the “standard approaches” in section 2.02.10 (flight patterns). - Initial approach speed will vary with ATC constraints and turbulence, but may be up to 240 Kts. - Initial approach speed may be maintained on a typical 3° glide slope to the following height above runway : NP

DECLARATION HEIGHT

(IAS x 10) ft

Configuration changes should be made at VLE VFE when decelerating. This procedure allows to reach VAPP speed at 500 ft above runway. Note : If deceleration rate on approach appears unsufficient, it is always possible to increase it by setting NPs on 100 OVRD, but at the expense of an increased interior noise.

LANDING In order to minimize landing distance variations the following procedure is recommended : Maintain standard final approach slope (3°) and final VAPP until 20 ft is called on radioaltimeter. F

F

At « 20 ft » call by PNF, reduce to FI and flare visually as required. Note : 20 ft leaves ample time for flare control from a standard 3° final slope. - During this flare the airspeed will necessary decrease, leading to a touch down speed of 5 to 10 kt lower than the stabilized approach speed.

F

As soon as main landing gear is on ground : - Control nose wheel impact. - Both PL : GI - Both LO PITCH lights : check illuminated. CAUTION : If a thrust dissymetry occurs or if one LO PITCH light is not illuminated, the use of any reverser is not allowed. In this case the propeller pitch change mechanism is probably locked at a positive blade angle, leading to a positive thrust for any PL position.

- Use foot brakes as required. - As speed reduces, and not later than about 40 Kt (estimated) Capt takes NWS control, co-pilot hold control column fully forward. Note : 1. Max reverse is usable down to full stop if required, but to minimize flight control shaking due to reverse operation at high power, it is helpful to release slowly PL back to GI when reaching low ground speeds (below 40 Kts estimated). 2. Max braking is usable without restriction down to full stop, whatever the runway conditions may be, provided ANTISKID is operative. R

3. In case of a significant bounce, a go around should be considered.

1. POWER UP The HT 1000 is directly powered by the DC BUS 1 or STBY BUS if TRU is installed. 2. FLIGHT PLANNING Two different routes can be prepared before each flight: RTE 1 may be used for the route from origin to destination and will be activated before take-off, RTE 2 may be used for the route from destination to alternate and will then be activated only in case of diversion. Before creating a route, make sure that the RTE 1 or RTE 2 pages have been completely erased. Selecting or re-selecting the origin airport will automatically erase the associated route. Details of the procedure to create a route are given in the Pilot's Guide. After activation of the route, the pilot initializes entrees via multifunction control system (MCDU). 3. NAVIGATION 3.1 General The HT 1000 basic navigation is provided by the GPS. When the GPS receiver is failed, deselected, or if the satellite coverage is insufficient, the navigation automatically reverts to the DME/DME mode or DR mode (based on the navigation solution hierarchy). Note : this DME/DME mode is available only if aircraft is equipped with two DME receivers. 3.2 Displays GNSS mode is selected by pressing the RNV pushbutton on the EFIS control panel. GNSS may be presented either in OBS mode or MAP mode. The selection is done by repetitive action on the MAP pushbutton of the EFIS control panel. OBS mode presents conventional lateral guidance on the active leg. In this mode the desired track selection is made by the HT 1000 (course selectors on glareshield panel are not operative). In MAP mode multiple Wpt and/or additional symbols as holding pattern, DME arcs and procedure turns will be presented. Note : Symbols do not reflect the exact path but indicate the type of path to fly. The to wpt" is displayed in magenta, all other wpt are white, a white track line connects the wpts.. The symbol for a holding pattern is an oval associated with a H letter. The symbol for a DME arc is a 90º arc with an arrowhead associated with a A letter. The procedure turns is displayed with 2 lines indicating inbound and outbound leg. Mod. : 5176

Note : GNSS is not coupled to the AP/FD in vertical mode. The vertical deviation is advisory only on the EFIS. Navigation monitoring - maintain HDG bug on actual aircraft heading - monitor the sequencing of the waypoints on the MCDU (ACT RTE 1/2 LEGS page) and make sure that there is no discontinuity. CAUTION : when flying over a WPT followed by a discontinuity, the AP will revert to the basic lateral mode, maintaining the wings levelled. The message CPL DATA INVALID" will then illuminate on the AFCS. CAUTION : when in LNAV mode, switching of AP/FD between Pilot and Copilot will disengage the LNAV mode even if both sides are in GNSS mode. LNAV mode can be reengaged. Navigation with OFFSET When a parallel offset has been activated OFS will be permanently displayed in cyan above the aircraft symbol when in MAP mode or in the left upper part of the EHSI when in ROSE/ARC mode. The leg presented on the MAP display is not the offset leg but the XTK value presented below the aircraft symbol is related to the offset. Therefore it is normal, in such a situation, to see the aircraft symbol aside the active leg with a XTK value showing 00.0 L/R. ETOPS operation Before ETOPS operation, a Fault Detection and Exclusion (FDE) check must be performed on the ground. Refer to Pilot's Guide for this procedure. Return to standard display: -

AHRS AHRS alignment sequence takes place as soon as the battery is switched ON, and it takes nominally 3 MINUTES DURING WHICH AIRCRAFT MUST NOT BE MOVED. To know the remaining time for AHRS alignment, depress AHRS FAST ERECT pushbutton. The heading which can be read on the associated EHSI indicate the time remaining (in seconds) for AHRS alignment (example : heading 090 = 1 minute and 30 seconds). Then release AHRS FAST ERECT pushbutton. AHRS normally survive to electrical transients asociated with engine start. R ON GROUND ONLY, if needed, AHRS reset may be performed by cycling all relevant C/B OFF-- ON. Note : the beginning of the 3 minutes alignment period may be observed as it is associated with a brief display of horizon tilted 30_ to the right without flag. CAUTION : resetting AHRS C/B in flight is not recommended as in flight reailgnment requires 3 minutes of very stable flight (which may be impossible to get in turbulence) and possibility of pulling the wrong C/B could lead to complete AHRS failure unrecoverable for the rest of the flight. Note : some of the AHRS failures observed in flight may be “self recoverable” when they are associated to a temporary failure of the SPERRY DIGITAL BUS. R CAUTION : Pilots must be aware of possible induced attitudes and heading errors in case of continuous turns, specially in high latitudes countries; therefore racetrack R holding patterns are to be flown rather than circles.

The APM analysis principle is to compare the aircraft theoretical drag with an ”in-- flight drag” computed with measured parameters available. Measured parameters used by the APM are acquired each second and are smoothed over a rolling average of 30 seconds to limit noise and error measurements. Then, the drag is calculated over a rolling average of 60 seconds. This means that the drag analysis alert would start after at least 90 seconds of parameter acquisition. The drag analysis starts as soon as the aircraft entered in icing conditions with landing gears and flaps retracted. The APM analysis will only be done with both engines operating. A cruise speed monitoring will also be conducted by comparing the measured IAS to the theoretical maximum cruise IASth. Different alarm messages will be delivered to the crew depending on the drag difference between computed drag and theoretical drag, and the speed difference between measured IAS and theoretical IASth. The alarm messages will not be delivered if the static air temperature is above 10 Celsius degree. 2.3.2.2. - APM Interfaces The APM electrical input / output interface is made of : - one ASCB bus input - one PCM FDAU input - four discrete inputs for weight rotary selector positions - one discrete output for alarm message : level 1 - one discrete output for alarm message : level 2 - one discrete input to monitor discrete output level 1 - one discrete input to monitor discrete output level 2 - one discrete output for APM FAULT - one discrete input for APM TEST

When the crew activated APM test, 2 discrete signals are sent, one to the MPC and one to the APIU, to test the APM functions and its interfaces. The APM test shall be performed by pushing and maintaining, for all test duration (maximum 5 seconds), the APM PTT TEST pushbutton on the 5 VU and the test result shall be as follows : - CRUISE SPEED LOW lights on 13 VU (both sides) illuminate - over 1 second later, DEGRADED PERF lights on 13 VU (both sides) illuminate, with CAUTION light and SC, with CRUISE SPEED LOW lights still illuminated - over 1 second later, INCREASE SPEED lights on 13 VU (both sides) illuminate flashing, with CAUTION light and SC, with CRUISE SPEED LOW and DEGRADED PERF lights still illuminated - over 1 second later, FAULT light on the 5VU illuminates, with CAUTION light, SC and ANTI-- ICING (on CAP), with CRUISE SPEED LOW, DEGRADED PERF and INCREASE SPEED lights still illuminated - end of test, the crew stop action on APM PTT TEST pushbutton, all lights shall extinguish.

R R

2.3.3 - NORMAL PROCEDURES 2.3.3.1 - Weight Selection and Computation Selection To determine the aircraft theoretical and ”in-- flight” performances the aircraft weight must be known. As the weight is not available, the crew must enter the take off weight value in the system with a twelve-- position rotary selector. This rotary selector can be moved after MPC is powered on, and after starting up of the two engines. On ground just before flight and as soon as the crew has computed the take off weight on the load sheet, the crew must select the corresponding weight by moving the rotary selector. It should be set to minimum weight then to take off weight nearest position.The take off weight will be taken into account by the system only if rotary selector has been changed. Note : Any change of rotary selector in flight will have no effect. Computation If the crew doesn’t select the take off weight before take off with the rotator, then the APM will perform a take off weight computation.This computation is performed during the first minutes of the flight and before the APM starts the drag analysis. The actual weight is then updated in flight by internal computation. ATR 42 Model : 400/500

3 - DMU (DATA MANAGEMENT UNIT) PART The DMU system is dedicated to the aircraft maintenance. The DMU has been designed to allow the user to customize the system according to his specific application, requirements, operating environment and logistics. Programming capabilities are provided, to allow modification of monitoring functions or implementation of additional monitoring functions. Most of the functions are configurable or programmable by an ”on-- ground” equipment called Ground Support Equipment (GSE), based on a Laptop. The GSE generates a customized DMU database, which determines the detailed functions of the DMU and is supplied to the DMU system via a PCMCIA interface. The DMU definition will be able to include two different ”customizations”: 1 - the customization basically performed by the supplier for answering ATR specification. 2 - the customization developped by the user through the GSE. The customization that are basically performed for ATR aircraft, activates the following functions: - ARINC 429 aircraft parameters acquisition. - Operational software and database upload from the PCMCIA interface. - Management of two APM discrete. - Management of PCMCIA QAR/DAR recording on a PCMCIA card. - Dialogue with a MCDU. - Management of a G-- Meter report. - Management of maintenance functions for various aircraft equipment.

4- OPERATIONS 4- 1 COMMON FEATURES FOR USE The Departure Clearance and D-- ATIS requests are to be prepared on MCDU in relevant ATS pages. In case of loss of data link capability, usual voice procedures will be used. When the crew is notified that there is no link with the ground station, ”NOCOMM” message, or in case of system failure, he must revert to voice procedures. Upon illumination of ”ACARS MSG” attention getter lights, the crew should check messages on MCDUs. The crew may have to send a new request or revert to voice procedures as required by ATS. 4- 2 DEPARTURE CLEARANCE DCL This service provides pilot with a data link departure clearance (DCL) within the scope of preset operational procedures. The DCL service should be initiated by the aircrew between 10 min and 3 min (or otherwise specified) before the clearance is needed. If DCL is not completed 3 min (or otherwise specified) before departure, the crew must revert to voice procedure. The Reclearance capability must not be performed by the DCL service. In the event of datalink reclearance being received, the Aircrew must ignore it and must revert to voice procedures. If the Aircrew is not able to accept the operational contents of the DCL message, he must revert to voice procedures otherwise he must send the Clearance Echoback message. A negative message may be sent back; in that case, the crew has to revert to voice procedure. Message content consistency The aircrew before take-- off must check the consistency of the SID delivered in the DCL message with departure runway and flight plan information. He must revert to voice procedures in case of inconsistency. Departure Clearance frequency has to be monitored in case a voice DCL back-- up procedure is necessary. All Departure Clearance delivered by voice supersede any datalink Departure Clearance message.

4- OPERATIONS (cont’d) 4- 3 DIGITAL ATIS D- ATIS Where a D-- ATIS is available, it supplements the existing Voice-- ATIS, the information are identical in both content and format and are updated simultaneously. The crew, after sending an ATIS request, must complete the ATIS service (reception) within 4 minutes or otherwise indicated. Otherwise, the crew must resubmit his ATIS request or revert to voice procedures. The crew must acknowledge receipt of the D-- ATIS answer at contact with ATC. For the crew, the voice procedures will be the back up of the D-- ATIS service. Message content consistency The crew must cross check the global consistency between D-- ATIS information parameters. In particular, the crew must check the name of the ATC airfield in the D-- ATIS request and in the ATIS message received The crew must check that radio communication and radio navigation means frequencies required by D-- ATIS are operational. The following data must be cross-- checked with Voice-- ATIS: - bird presence and presence of artificial obstacle on selected runway, - meteorological and wind data for landing, - type of approach, - active runway, - dew point temperature, - altimeter setting.

FOREWORD Procedures contained in this chapter are recommended by the manufacturer. They are consistent with the other chapters of this manual, in particular 2.02 PROCEDURES AND TECHNIQUE. Normal procedures are not certified by the Authorities, and in the judgment of the Manufacturers, are presented here in, as the best way to proceed from a technical and operational stand point. They are continuously updated, taking into account inputs from all operators and lessons of the Manufacturer’s own experience. In the same manner, they may be amended as needed by the Operator. However if the FCOM is used as the on board Operational Manual, the Manufacturer recommends channeling any suggested amendment through him for early publication so as to maintain the consistency of the Manual. The Operator should be aware that a complete rewriting of this chapter may be done under his own responsability but could lead to difficulties in updaing and maintaining the necessary homogeneity with the other chapters of this manual.

PRELIMINARY The following sections provide expanded information related to normal procedures. Normal procedures consist of inspections, preparations and normal check lists. All items are listed in a sequence following a standardized scan of the cockpit panels (see section 2.03.03) except when required by the logic of actions priority, to ensure that all actions are performed the most efficient way. Normal procedures are divided into phases of flight and accomplish by recall. In the following assignation : - CM1 refers to the Crew Member in the left hand seat - CM2 refers to the Crew Member in the right hand seat - PF refers to the Pilot Flying - PNF refers to the Pilot Non Flying After completion of a given procedure, the related normal check list is used. The normal check list developed by the manufacturers includes only the items that may have a direct impact on safety and efficiency if not correctly accomplished. All normal check lists are initiated at the Pilot’s flying command. Some normal procedures which are non routine will be found in chapter 2.02 PROCEDURES AND TECHNIQUE and in chapter 3.11 SPECIAL OPERATIONS. All steps have to be performed before the first flight of the day or following a crew change or maintenance action. Transit steps are the only ones to be completed after a transit stop. They are grouped inthe COCKPIT FINAL PREPARATION. If there is any doubt as to whether the application of transit procedures covers all safety aspects, the complete preparation must be accomplished.

R REDUCED POWER SETTING IN CRUISE The airline, according to its cost policy, can choose to cruise at reduced power, e.g. at long-- range power or given IAS. The associated cruise derated tables need to be available on board for the flight crew. Those tables can be published with the FOS Module 2, In-- flight performance, as shown in example in Figure 1. The PLs are set according to the torque given in the tables. This requires a PL adjustment out of the notch. Limitations: The reduced power cruise is not allowed in case of icing conditions, as the IAS may already be decreased due to ice accretion on the airframe. In case of an engine failure, the PLs need to be immediately moved back into the notch, power management to MCT. From a maintenance point of view, reduced power operations may achieve lower engine overhaul costs as a result of the reduced power settings.

PROCEDURES INITIATION - No action will be taken (apart from depressing MW pb): . Until flight path is stabilized. . Under 400 ft above runway (except for propeller feathering after engine failure during approach at reduced power if go around is considered). - Before performing a procedure, the crew must assess the situation as a whole, taking into consideration the failures, when fully identified, and the constraints imposed. ANALYSIS OF CONSEQUENCES OF A FAILURE ON THE FLIGHT Basic airmanship calls for a management review of the remaining aircraft capabilities under the responsability of CM1.

COMMENTS - Safety analysis leads us to consider the case when the DUAL DC GEN LOSS is subsequent to : . Single engine operation, and . DC GEN inoperative on the live engine. In that case HYD GREEN PUMP has to be set to OFF position in order to overload the live ACW generator. - Selecting TRU ON allows to recover EMER, ESS and STBY (AC and DC) busses supply from ACW generators. - Minimum cabin light must be switched OFF to limit the electrical load of the TRU. - As DC BUS 1 is lost, automatic pressurization is lost. - Both stick pusher and stick shaker are lost without FAULT alarm. - STBY BUS undervoltage may occur due to a failure of the STBY BUS system circuit. In this event, the OVRD function may be used to transfer the STBY BUS supply from the MAIN BAT BUS to the EMER BAT BUS. R - TLU AUTO mode is lost and MAN mode must be used. MAN mode acts on TLU standby actuator which remains povered even if TLU is in LO SPD established position. When R TLU SW is set to AUTO position, TLU standby actuator electrical power is off. R R - PA must be used for pax instructions because cabin signs are not supplied in emergency. R

But if structural damage is suspected, use the flight controls with care and reduce speed as appropriate. Landing gear may be extended in order to increase rate of descent. - Notify ATC of the nature of the emergency encountered and state intentions. In the event ATC cannot be contacted, select code A77 or transmit the distress message on one of the following frequencies (VHF) 121,5 MHz or (HF) 8364 KHz. Only VHF 1 is available on battery. - CL are selected 100% OVRD to increase drag and consequently to increase the rate of descent.

Water splashing and streaming on the windshield . Unusually extensive ice accreted on the airframe in areas not normally observed to collect ice . Accumulation of ice on the lower surface of the wing aft of the protected areas . Accumulation of ice on propeller spinner farther aft than normally observed The following weather conditions may be conducive to severe in-flight icing : . Visible rain at temperatures close to 0_C ambient air temperature (SAT) . Droplets that splash or splatter on impact at temperatures close to 0_C ambient air temperature (SAT)

COMMENTS R

- Since the autopilot may mask tactile cues that indicate adverse changes in handling characteristics, use of the autopilot is prohibited when the severe icing defined above exists, or when unusual lateral trim requirements or autopilot trim warnings are encountered while the airplane is in icing conditions. - Due to the limited volume of atmosphere where icing conditions usually exists, it is possible to exit those conditions either : . by climbing 2000 or 3000 ft, or . if terrain clearance allows, by descending into a layer of air temperature above freezing, or . by changing course based on information provided by ATC.

GENERAL The procedures following failures represent the actions applicable after a failure to ensure adequate dafety and to ease the further conduct of the flight. They are applied according to the “Read and Do” principle except for the memory items. PRESENTATION The procedures are presented in the basic check list format with an adjacent expanded section which provides: - indication of the particular failure, alert condition - explanation for actions where the reason is not self evident - additional background information The abbreviations used are identical with the nomenclature on the cockpit panels. All actions are printed in CAPITAL letters. R Q : a preceding black square is used to identify a pre-- condition (in bold) for given action(s). R O : a preceding black dot is used to indicate the moment (in bold) when given action(s) have to be applied. TASK SHARING For all procedures, the general task sharing stated below is applicable. The pilot flying remains pilot flying throughout the procedure. PF, Pilot Flying, responsible for: - PL - flight path and airspeed control - aircraft configuration - navigation PNF, Pilot Non Flying, responsible for: - check list reading - execution of required actions - actions on overhead panel - CL - communications The AFCS is always coupled to the PF side (CPL selection).

PROCEDURE INITIATION - No action will be taken apart from depressing MC / MW pushbuttons: . until flight path is stabilized . under 400 ft above runway except propeller feathering after engine failure during approach at reduced power if go around is considered - At flight crew discretion, one RESET of a system failure associated to an amber caution may be performed by selecting OFF then ON related pushbutton. If the failure alert disappears, continue normal operation and RECORD the event in the maintenance log. If not, APPLY the associated following failure procedure. - Before performing a procedure, the crew must assess the situations as a whole, taking into consideration the failures, when fully identified, and the constraints imposed. ANALYSIS OF CONSEQUENCES OF A FAILURE ON THE FLIGHT Basic airmanship calls for a management review of the remaining aircraft capabilities under the responsability of CM1. CCAS When TO INHI has been selected, until the first leg of landing gear unlocks, all alerts are inhibited except: R WARNING - ENG 1 FIRE - ENG 2 FIRE - CONFIG - FLAPS UNLK - LDG GEAR NOT DN - EXCESS ALT - EXCESS CAB ∆P - PITCH DISCONNECT - PROP BRK (if applicable) CAUTION - EFIS COMP ADVISORY - PRKG BRK - GPWS - MAINT PANEL

FTR THEN FUEL SO COMMENTS - In case of tailwind component greater than 10 kt and just after engine start, propeller must be unfeathered rapidly to take advantage of the wind created by propeller rotation and consequently to avoid exhaust gas return flow in the nacelle. - When taxiing with tail wind component, use of reverse requires special care as air flow created by propeller reversing combined with tail wind will induce an exhaust gas return flow which may damage the nacelle. It is consequently recommended not leave PL in reverse position for any period of time exceeding 10 seconds. - NAC OVHT alert is inhibited when both wow systems detect aircraft airborne.

ONE EEC FAULT / BOTH EEC FAULT (CONT’D) COMMENTS in common for both procedures - With EEC OFF, the automatic relight is not available on affected engine(s). - For PW121A only : EEC OFF operation, combined with BLEED OFF operation, may lead to engine stall which may be prevented through slow power movements, especially when advancing PLs. - For PW121A only : an engine stall is indicated by mild surge(s). This will normally stops without crew action, however a slight power reduction may be considered to restore normal operation. ONE EEC FAULT (CONT’D) COMMENTS specific for ONE EEC FAULT - When EEC fails, two cases must be considered : High Power Low Power PL set forward 52_ PL set aft of 52_ in green sector EEC FAULT light flashes, NH is EEC FAULT comes on steady, EEC is automatically frozen to its prior value (FAIL automatically deselected (Automatic FIX) reversion) - Feathering the engine with EEC failed for taxi and static operation will avoid prolonged time in NP restricted band (propeller limitation). BOTH EEC FAULT (CONT’D) COMMENTS specific for BOTH EEC FAULT - During reduction at touch down, both ACW GEN may be lost and therefore both main HYD pumps. - Both digital torque indications are lost when TQ are below 20%. - To avoid operating propellers in the NP restricted band, it is recommended to taxi with one engine with NP > 63%.

External causes such as icing, very heavy turbulence, fuel mismanagement. These causes, which may affect both engines can generally be easily determined and an immediate relight can be attempted. . Internal causes which as engine stalls or failures usually affect a single engine and are not so easily determined. In these cases, the engine is shut down then the cause of the flame out investigated. If it cannot be positively determined what caused the flame out, the need for engine restart should be evaluated against the risk or further engine damage or fire that may result from a restart attempt. - If damage is suspected, as precautionary measure, the FIRE handle is pulled.

APPLY COMMENTS - Normal steady oil temperature is in the range 71/99_C. - Increased power setting may reduce the OIL TEMP due to the increase of fuel flow across the fuel/oil heat exchanger. - If an OIL TEMP rise occurs in steady state condition a failure of the oil cooler flap may be suspected, if no other engine malfunction is noted. In this case reducing power may limit temperature excursion.

ENG OIL LO PR (CONT’D) COMMENTS - Engine oil low pressure is identified thanks to two low pressure detectors : . the first one is connected to the CCAS (MW+CRC+ENG OIL red light on CAP) . the second one is connected to the local alert (analogic oil low pressure indication + associated red light) - If the CONT RELIGHT (if installed) is ON when the CL is moved from FUEL SO to FTR, the combination of a fuel flow and active igniters may lead to an unintentional relight or to an overtemperature (ITT) condition. - If CCAS only is activated, alert must be disregarded, oil press local alert indication must be constantly monitored during flight. - If local alert only is activated and provided ENG OIL low pressure alert on CCAS is checked operative, twin engine operation should be resumed. - NP > 10% after a shut off procedure may indicate an incomplete feathering. In this case, the approach speed is increased to compensate the extra drag of the incompletely feathered propeller, and, on aircraft not fitted with PEC, IAS is limited in order not to exceed the maximum allowed NP.

LANDING WITH ABNORMAL LDG GEAR (CONT’D) COMMENTS - The procedure is intended for use when one or more landing gear fail to extend and/or lockdown following the application of either normal or gravity extension procedure. It is considered preferable to use all available gear locked down rather than carry out a belly landing. Under these circumstances, a hard surface runway landing is to be recommended. Full advantage should be taken from foam spread on the runway. - Notify ATC of the nature of emergency encountered and state intentions. - Notify the cabin crew of the nature of emergency encountered and state intentions. Specify the available time. - GPWS is selected OFF to avoid nuisance warnings. - Burn fuel off down to the minimum possible impact weight. This reduces VAPP and as a consequence the load factor for impact and the energy which must be dissipated.

RELEASE COMMENTS - The OVRD mode allows to operate engines and airframe dual distribution valves in case of engine boots primary control failure. - DE-- ICING MODE SEL OVRD must be used if there is evidence of boots cycling malfunctionning even if DE-- ICING MODE SEL FAULT is not illuminated. - When DE-- ICING MODE SEL is selected to OVRD, ENG and AIR FRAME FAULT lights are inhibited and boots cycling operated only according to FAST mode. R - In case of DE-- /ANTI-- ICING ENG FAULT and after a prolonged flight with considerable accretion, it is possible that when setting the DE-- ICING MODE SEL to OVRD, the engine may ingest the build up ice and a flame out could occur. As the functionning of this device is sequential (i.e. the two engines are not concerned at the same time), it is suggested to release the DE-- ICING MODE SEL pushbutton before the same phenomenon occurs on the second engine.

INTRODUCTION The engine power control is achieved by power lever (PL) and condition lever (CL). These controls act on three main components: - Propeller Electronic Control or PEC - Hydromechanical Unit or HMU - Engine Electronic Control or EEC The main engine power setting parameter is torque. The maximum torque value for a given flight phase is defined by the FDAU and displayed by a bug (FDAU target) on torque indicator. The crew has to set the R PWR MGT selector to the position corresponding to the flight phase and to set R the power lever in the notch or on the ramp in case of GO AROUND or for TO in R uptrim inoperative case : in these conditions, the controlled torque matches the maximum target torque displayed by the FDAU (except for TO position : TO power is delivered but RTO power is displayed by the automatic bug). R ENGINE RATINGS Take-off This rating corresponds to the normal, derated take-off thrust. It is normally time limited to 5 minutes. Reserve take-off This rating corresponds to the maximum thrust certified for take-off. It is automatically selected by the ATPCS system in case of engine failure. Time limit is 10 minutes. Maximum continuous The maximum continuous rating corresponds to the maximum thrust certified for continuous use. IT MUST ONLY BE USED TO ENSURE SAFE FLIGHT IN CASE OF EMERGENCY, PARTICULARLY ENGINE FAILURE. Maximum climb The maximum climb rating corresponds to the maximum thrust approved for normal climb operation. Maximum cruise The maximum cruise rating corresponds to the maximum thrust approved for normal cruise operation. Go around It is the maximum rating authorized for go-around.

AA

The methodology for the determination of the maximum take off weight is described in the chapter 6-03 of the Airplane Flight Manual, which is the official reference. As this way is long and complex, ATR pilots and dispatchers may have two other possibilities to improve efficiency : - the methodology described in 3-03-02 that gives non optimized results but can be used on board - the Regulatory Take-Off Weight (RTOW) charts, generated with the Flight Operations Software (FOS), that give very accurate results before the flight. TAKE-OFF CONDITIONS Different weather conditions may be encountered at the take-off : D NORMAL CONDITIONS D ATMOSPHERIC ICING CONDITIONS Atmospheric icing conditions exist when OAT on the ground and for take-off is at or below 5°C or when TAT in flight is at or below 7°C and visible moisture in any form is present (clouds, fog with visibility of less than one mile, rain, snow, sleet and ice crystals). D GROUND ICING CONDITIONS Ground icing conditions exist when OAT on the ground is at or below 5°C and when surface snow, standing water, or slush is present on the ramps, taxiways and runways. Note : TAKE-OFF IS PROHIBITED when frost, snow or ice is adhering to the wings, control surfaces or propellers. Different runway conditions may be encountered : D dry D wet (less than 1/8 inch or 3 mm of water) R R R

D contaminated by : - water or slush between 1/8 and 1/2 inch (3 and 12.7 mm) - loose snow, must be considered as slush. To determine the equivalent slush depth, multiply the loose snow depth by : 1.25 x (actual loose snow density) - compact snow - ice D damp : a runway is damp when it is not perferctly dry, but when the water does not give it a shiny appearance. For a damp runway, we do not consider any performance limitation.

METHODOLOGY

001 NOV 00

AA

The quick reference tables QRT (3.03.04) are to be used in relation with the method described in 3.03.02 page 3 by the airlines that do not have the FOS. The QRT are RTOW charts computed with the FOS, but not optimized. F

In case of non limiting (NL) runway, the maximum take-off weight is the maximum structural take-off weight and the take-off speeds must be read in the 3.03.05 chapter or in the quick reference handbook, associated with the actual take-off weight.

F

In case of limiting runway, a maximum take-off weight and the associated speeds are provided in the chart. The limitation is indicated under a specific code form : 1 = structure 5 = tyre speed 2 = 2nd segment 6 = brakes energy 3 = runway 7 = runway 2 engines 4 = obstacle 8 = final take-off

The limitation code appears always twice in order to cover optimization taking into account two simultaneous limitations (2-2 means 2nd segment only ; 2-4 means both 2nd segment and obstacle limitation). The actual take-off weight must be less or equal to the computed maximum take-off weight. R The take-off speeds to be used must be speeds indicated in the chart, even if the actual weight is lower than the computed weight. Note : Due to the conservative definition of NL area a gap can be encountered between NL speeds and FOS optimized speeds when the computation case is at the NL border.

AIR CONDITIONING Take off performances are computed with AIR CONDITIONING ON. To take into account the effect of AIR CONDITIONING OFF add to the runway length the ∆L correction given in the following table :

LENGTH AIR COND. ON

∆L AIR COND. OFF

750 m (2460 ft) 1000 m (3280 ft) 1500 m (4920 ft) 2000 m (6560 ft) 2500 m (8200 ft) 3000 m (9840 ft)

0 m (0 ft) 10 m (30 ft) 25 m (80 ft) 45 m (140 ft) 65 m (210 ft) 85 m (270 ft)

Note : The FOS, in accordance with AFM, takes into account a conservative performance decrement linked to the thermodynamical limitation of the engine. If the day conditions authorize a mechanical limit operation of the engine (i.e torque bleed ON = 90 % for TO and 100 % for RTO), the take off may be performed air conditioning ON without performance penalty.

RUNWAY SLOPE ¯ Runway slope between - 2 % and + 2 % Decrease the runway length by 700 m (2300 ft) for 1 % uphill slope. For a better accuracy, use the chart given in 3.03.02 page 5 or 6. ¯ Runway slope beyond 2 % Refer to AFM and apply the given correction. WIND Decrease the runway length by 500 m (1640 ft) for 10 kt tailwind. QNH To use a chart computed at the standard pressure when the actual QNH is not standard, follow the hereafter procedure : 1) With the actual wind and temperature, if necessary corrected by air conditioning influence, enter the chart and read the take-- off weight and the associated limitation. 2) Apply the QNH correction : ¯ QNH > 1013.25 HPa or 29.92 in Hg No credit in case of brakes energy limitation, keep the values of the chart. For all other limitations, add 70 kg (155 lb) to the TOW for each 10 HPa (0.29 in Hg) above the standard pressure. For QNH  1050 Hpa, keep the values of 1050 HPa. ¯ QNH < 1013.25 HPa or 29.92 in Hg Substract 265 kg (585 lb) to the TOW for each 10 HPa (0.29 in Hg) below the standard pressure. 3) With the new TOW, enter again the chart to interpolate the take off speeds.

NON DRY RUNWAYS A non dry runway may be : - wet, - contaminated by water or slush, loose snow*, compacted snow, ice. *Loose snow : must be considered as slush. To determine the equivalent slush depth, multiply the loose snow depth by : 1.25 x (actual loose snow density) 1 - Contaminated runway At take off, the aircraft lateral controllability depends on : - the exact contaminant characteristics, - the cross wind component, - the runway width and visual references. Since these factors do not allow sufficient accuracy for predicting the effect of asymmetrical reverse thrust, it is therefore not recommended to use single engine reverse thrust for take off on contaminated runway. Performances without reverser only are to be used for flight preparation. 2 - Wet runways In this particular condition, the single reverser use is perfectly controllable and leads to the minimum stop distance in case of rejected take off. 3 - Non dry runways corrections for FCOM computation According to the previous assumptions, decrease the runway length by the following values to take into account the runway contamination : RUNWAY CONTAMINATION

AA

The QRT are computed at standard pressure, with air conditioning ON, no wind, no obstacle, a dry runway and no slope. Entry parameters must be determined as indicated in 3.03.02 page 3. NORMAL CONDITIONS The QRT are computed with V2/VSR = 1,143 and V1/VR = 1. ICING CONDITIONS The QRT are computed with V2/VSR = 1,222 and V1/VR = 1. In case of ground icing conditions, if atmospheric icing conditions do not exist, the V2/VS speed ratio may be the same as in normal conditions. Note : All regulatory limitations are taken into account in the QRT, except the structural limitation. When the QRT indicates a weight value above the certified structural value, that means that the runway is NL in the conditions of computation of the QRT. In any cases, the actual TOW must always be less than the certified MTOW associated to the operated ATR version.

CAUTION 1. FOS results must be verified against the Airplane Flight Manual performance data. In case of any discrepancy, the AFM performance data shall prevail. 2. It is the Operator's responsibility to update this chart in case of any change in runway or obstacle characteristics or in case of amendment of the AFM performance data. Example 1 : . Tail wind : 5 kt . ATOW : 18 t . Temperature : 15_C . QNH : 1013.25 hpa Check ATOW below 18511 kg, which is the maximum weight possible (Regulatory Take Off Weight because of the runway limitation) The take off speeds associated to the ATOW are :

Example 2 : Same conditions as in example 1 but with QNH=1023.25 hpa The RTOW is equal to 18511+88=18599 kg The take off speeds associated to the ATOW are :

V1 = 106 kt Vr = 107 kt V2 = 113 kt

V1 = 106 +1=107 kt Vr = 107 kt V2 = 113 + 1 = 114 kt

Example 3 : . No wind . ATOW : 18 t . Temperature: 0_C . QNH : 1003.25 hpa The runway is NL (Non Limiting) Therefore, the RTOW is equal to the maximum structural take off weight of 18600 kg. Check ATOW below 18600 kg. Read the speed associated in FCOM 3.03.05 p2 ATR 42 Model : 400/500

Climb charts are established for two indicated speeds (160 kt, 190 kt) and for standard temperature (ISA) at Climb Power with Air conditioning in normal mode. Corrections are given to take into account the temperature effect. When using air conditioning in high mode, increase fuel consumption by 6.5 % (160 kt) or 8.5 % (190 kt). All charts are established with a center of gravity location corresponding to 25%. OPERATIONAL CEILING The operational ceiling is the maximum altitude which can be reached with a minimum R rate of climb of 300 ft/mn (see 3.04.02 p 1). This is the recommended cruise altitude to R minimize the fuel consumption. CLIMB IN ICING CONDITIONS Atmospheric icing conditions exist when TAT in flight is at or below 7°C and visible moisture in any form is present (clouds, fog with visibility of less than one mile, rain, snow, sleet and ice crystals). Climb charts in icing conditions are established for 160 kt at climb Power with Air conditioning in normal mode. Performance are computed taking into account a degradation of aircraft aerodynamic at altitudes where icing conditions may be encountered. That is why tables are given for different temperatures (ISA-- 20, ISA-- 10, ISA, ISA + 10, ISA + 20). The icing operational ceiling is computed for a minimum rate of climb of 100 ft/mn and can be read directly on the tables (3.04.04 pages 1 to 10) just below a blank division. The maximum operational ceiling (twin engine) which is accessible when flying at VMLBO = 1.45 VSR is given in 3.04.04 p.11. Since computed with a lower residual rate of climb in icing conditions than in normal conditions, the operational ceiling may sometimes be greater in icing conditions. IN THIS CASE DO NOT EXCEED THE CEILING COMPUTED FOR NORMAL CONDITIONS. Note : All performance data given for ICING CONDITIONS derive from flight tests measurements performed with ICE SHAPES representative of the worst icing cases considered by certification and applicable losses of propeller efficiency. Because of the variability of REAL ICING, climb performance published for icing conditions MUST BE regarded as operational information only.

INTRODUCTION The Standard Instrument Departure Procedures (SID) can require a climb gradient to clear obstacles or to join a flight level at a given distance. The gross climb gradients are displayed in the following graphs for : -One engine out - one engine at Maxi Continuous Power - IAS = Final Take Off Speed -Two engines at Max Climb Power - IAS = 160 kt -Two engines at Max Climb Power - IAS = VMLB DIRECTION FOR USE If a departure requires a climb gradient X% between the two altitudes Z1 and Z2 (Z2>Z1) : -if the climb gradient at Z2 (the highest altitude) is better than X, then the procedure can be applied -if the climb gradient at Z2 is lower than X, then determine the climb gradient at 0.5x (Z1 + Z2): - if the climb gradient at 0.5x(Z1 + Z2) is better than X then the SID procedure can be applied - if the climb gradient at 0.5x(Z1 + Z2) is lower than X then the SID can not be used

CRUISE P1 INTRODUCTION

100 APR 08

AA

Cruise charts are established from FL 60 to FL 250 for different ISA conditions with air conditioning in normal mode. As soon as flight level is reached, select PWR MGT on CRZ position. When using air conditioning in high mode increase fuel consumption by 3 % and subtract 5 kt on True Airspeed. All charts are established with a center of gravity location corresponding to 25 %. Max cruise tables are given with NP = 82 %. CRUISE IN ICING CONDITIONS Atmospheric icing conditions exist when TAT in flight is at or below 7°C and visible moisture in any form is present (clouds, fog with visibility of less than one mile, rain, snow, sleet and ice crystals). Tables are established only for the altitudes where icing conditions may be encountered and for different temperatures (ISA - 20, ISA - 10, ISA, ISA + 10, ISA + 20). Note : All performance data given for ICING CONDITIONS derive from flight tests measurements performed with ICE SHAPES representative of the worst icing cases considered by certification and applicable losses of propeller efficiency. Because of the variability of REAL ICING, cruise performance published for icing conditions MUST BE regarded as operational information only.

AA

Holding charts are established : - in clean configuration - with air conditioning in normal mode. - with NP = 82 % propeller speed - at VmHBO of icing conditions. This minimum manoeuvring speed covers the whole flight envelope in normal conditions and in icing conditions without appreciable increasing of consumption. When using air conditioning in high mode, fuel consumption is increased by 3 %. All charts are established with a center of gravity location corresponding to 25 %. The temperature effect is negligible. ICING CONDITIONS Atmospheric icing conditions exist when TAT in flight is at or below 7°C and visible moisture in any form is present (clouds, fog with visibility of less than one mile, rain, snow, sleet and ice crystals).

Two kinds of descent are proposed : D at given rate from cruise altitude, descent at 1500 ft/mn (or 2000 ft/mn with pressurization in FAST mode) 1) set power to reach the desired descent speed 2) maintain descent speed and rate of descent R R R

D at given gradient from cruise altitude, descent at chosen gradient (3° with pressurization in NORMAL mode, 4° or 5° with pressurization in FAST mode) 1) set power to reach the desired descent speed 2) maintain descent speed and gradient of descent From 1500 ft to final landing, the tables are calculated with time and fuel allowances of : - 3 mn for the time - 30 kg (66 lb) for the consumption WEIGHT CORRECTION - Increase the fuel consumption by : + 2.5 % at 1500 ft of rate of descent + 5.0 % at 2000 ft of rate of descent + 2.5 % at 3° descent gradient + 3.5 % at 4° descent gradient + 5 % at 5° descent gradient for a 1000 kg (2200 Lb) weight decrease - No correction for weight increase - No influence on time and distance

CORRECTION ON LANDING DISTANCES - Wind

: S dry or wet runway add 10 % per 5 kt tailwind subtract 2 % per 5 kt headwind S contaminated runway add 12 % per 5 kt tailwind subtract 3 % per 5 kt headwind

- Airport elevation : S dry or wet runway add 3 % per 1000 ft above sea level S contaminated runway add 5 % per 1000 ft above sea level - Effect of reverse : landing distances are decreased by S 5 % on dry runway S 13 % on wet runway R S 13 % on runway contaminated by water or slush R S 12 % on runway contaminated by compact snow R S 29 % on runway contaminated by ice R

CAUTION : On contaminated runway, performances without reverser only are to be used for flight preparation. Note : Landing on damp runway. A runway is damp when it is not perfectly dry, but when the water which is on it does not give a shiny appearance. For damp runway, we consider no performance limitation.

- Runway slope (applicable between - 2 % and - 4.5 %) S Tailwind limit = 5 kt R S Flaps 35 only Add 40 m (130 ft) to the actual landing distance for each 1 % of down hill slope. Example : . Runway slope = - 3 % . Actual landing distance = 1200 m Corrected landing distance = 1200 + (3 x 40) = 1320 m S Refer to AFM for a better accuracy

The height above the ceiling is : 25000 - 16800 = 8200 ft. ⇒ Refering to page 7, the distance to reach the ceiling of 16800 ft is : 220 - 45 = 175 NM.

PROCEDURE J

If obstacle problem exists

In order to maintain the highest level possible, the drift down procedure should be used : D MCT on operative engine R D Action related to decision points D Deceleration in flight level down to drift down speed which then will be maintained (IAS mode) - In normal conditions VMLB0 - In icing conditions VMLB15 (flaps 15 will be selected when below VFE) D LO BANK mode selection - If, having reached drift down ceiling altitude, obstacle problem persists, the drift down procedure is continued to make an ascending cruise. - If, after drift down, obstacles are cleared, the subsequent cruise will be performed using MCT thrust on the remaining engine and the 1 engine cruise tables. When possible FL 70/80 is recommended in order to optimize the cruise speed. Note : A special attention should be paid to the fuel unbalance. It is recommended to balance the tanks using the fuel crossfeed when the dissymmetry reaches 100 kg (or 200 lbs).

If no obstacle problem exists

Drift down procedure is not necessary. A descent at maximum continuous power will be performed at 200 kt IAS. When the vertical speed slows down to 500ft/mn maintain this value by increasing the speed. Aircraft will be levelled when reaching the chosen cruise altitude. R When possible, FL 70/80 is recommended in order to optimize the speed. Use 200 kt IAS descent tables (3.09.16 or 17) and 1 engine cruise tables (3.09.20 or 25).

GENERAL Extended overwater flight is not allowed. It is necessary to take into account the increased drag to determine the take-- off weight and fuel consumption. FLIGHT IN ICING CONDITIONS IS PROHIBITED WITH GEAR DOWN The propeller speed used is 82 %. Refer to the MMEL for the operating procedures. DETERMINATION OF MAX TAKE OFF WEIGHT Penalties on performance affect the WAT ; Enter in the quick reference tables with Weight reduction 15 %. APPROACH CLIMB PERFORMANCE Decrease the basic limiting weight by 11 %. FLIGHT PLANNING Climb Climb at VmHB0 icing (1.5 VSR) with both engines at maximum climb power setting. The tables in 3.11.01 p 2 to 5 give the time, distance and fuel consumption according to take-- off weight. Cruise The maximum recommended altitude is 16000 ft. The maximum cruise speed is 165 kt. Pages 3.11.01 p 6 to 9 give cruise tables at this maximum speed. Obviously, the ceiling on one engine may be a limiting factor, and the choice of the route should reflect this concern. Engine failure The weight penalty on single engine ceiling computation is 15 %, consequently decrease the single engine ceiling by : ACTUAL WEIGHT KG (lb)

AA

R Operations Engineering Bulletins, OEB, are issued by ATR, under supervision of Flight Test Department, as the need arises to transmit in advance technical or procedural information before technical solutions is developped and implemented.ALL OEB are R distributed to ALL FCOM holders.Information in OEB is responsibility of ATR in the same manner as the whole FCOM, and may not be approved by Airworthiness Authorities at the R time of release.In case of conflict with the certified Flight Manual, the latter will R supersede.When an operator implements a modification cancelling an OEB, this operator may not take into account this OEB anymore for the concerned aircraft.

O.E.B. N° 1 DESCRIPTION

P1 001 Issued by SEP 95 BTV/PN

AA

SUBJECT : (ON GROUND) PROPELLER BRAKE AND ENGINE SHUT-OFF PROCEDURE 1 - Reason for issue A quick engine shut-off or propeller brake application after the propeller feathering may induce an undue PEC FAULT warning. 2 - Background information If the engine is shut-off or the propeller brake applied too early after the propeller feathering, the subsequent oil pressure loss does not allow the propeller blades to reach the correct feather pitch angle. This will induce a discrepancy detection by the PEC internal monitoring, thus causing an undue PEC FAULT warning. 3 - ATR action ATR WILL ISSUE A MODIFICATION TO ELIMINATE THIS PROBLEM, NO LATER THAN MAR 96. 4 - Procedure Before shutting off an engine or applying the propeller brake, allow a 30 seconds minimum delay after the feathering action.

Validity : All ATR 42 model 500 until further notice ATR 42 Model : 500

O.E.B. N° 7 DESCRIPTION AA

DEC 05

SUBJECT : PEC OFF operations 1. REASON FOR ISSUE In the PEC OFF condition, if the NP becomes inferior to 77% at idle power, the engine eventually will not spool up when advancing the power lever. 2. BACKGROUND Np < 77% at idle power is never reached at normal operating speeds, therefore this problem could only be met in training flights during stall exercices or touch and go maneuvers. 3. ATR ACTION Implementation of modification 4883 or SB ATR42-- 73-- 0007 cancels this OEB. 4. PROCEDURES - Flight at airspeeds inferior to 90kt is prohibited in the PEC OFF condition - Training : In the PEC OFF condition touch and go and stall maneuvers are prohibited.

Validity : For model 42-- 500

SUBJECT : STATIC INVERTER DOUBLE LOSS 1 - Reason for issue Warning to crew before modification application. 2 - Applicability All aircraft not fitted with modification 5544. 3 - Background information In flight it is difficult to identify which bus is in short-- circuit. Considering also the particular pilot workload following system failure and that several circuit breakers must be opened for the faulty unit isolation. 4 - ATR action A modification is already defined and must be applied for OEB cancellation. 5 - Procedures Note : ATR recommend application of SB ATR42-- 24-- 0055 (mod 5546) which facilitates identification of involved C/B by means of orange caps.
