1 Introduction The Electronic Flight Strip (EFS) is one component of the ATM Aircon system. Its aim is to support a work environment that allows the controller to observe and manage the Flight Plans involved with the Aerodrome. This environment is an electronic recreation of the controller classical desk and paper flight strips. Besides this, the EFS System is integrated with the subsystems that manage Flight Plans, Gates Assignments, Radar Data, Aerodrome Status Information, Meteorological Messages so that, all the information affecting a certain flight is easily reachable by the controller.

1.1

Horizontal scrolling: it is used to display and select values from a list. The values are displayed by means of two arrows, right and left, to increase or decrease the default value. An example of this horizontal scrolling is shown in following figure:

Figure 2-1: Example of “Horizontal scrolling” In the EFS it is available horizontal scrolling for TIME, Heading, Level and so on.

2.2

Electronic Flight Strips Description

The Electronic Flight Strip comes to substitute the classic Printed Flight Strip typically used at control centers. However, a backup Paper Flight Data printing capability is provided in case of the EFS functionality becoming unavailable in the system. The EFS contains information about a flight’s progress and current status. The strips are displayed on the specific working positions to communicate the flight information to the responsible controllers. Each EFS presents the information in pre-defined fields. There are two types of EFS as described in the following table: Table 2-2: Flight Strip Types Type of Flight Strip

2.2.1.2 Runway Allocation Field The management of this field is described through the following points: 1. IT opens a pull down menu of possible runways (see following figure). 2. The selected runway determines the SIDs (Standard Instrument Departures) and Holding Points available through other menus.

Figure 2-4: Allocation Runway Pull Down Menu In system configuration files, each runway has its associated taxi zones (that can be defined as a normal taxi zone or a de-ice taxi zone), and its gates.

2.2.1.3 SID / VFR Field (Standard Departure Procedure Assigned) The management of this field is described through the following points: 1. Displays the assigned Standard Departure procedure (SID), or VFR route if the EFS corresponds to a Local flight. 2. Left button mouse click opens a pull down menu containing the SIDs for the allocated runway and a VFR option (see Figure 2-6). For Local EFS, the pull down menu displays all the VFR routes available. Right button mouse click allows to insert an alternative departure instruction. 3. If the flight is VFR, a “frame” is displayed surrounding the field. 4. The flights departing in DCT (without SID assigned) have this field displaying the first route point. If this point is designated by latitude/long., only the first seven characters are displayed. 5. Provides access to the triple pop-up menu of SID, LEVEL and HEADING. A RIGHT mouse button click opens a pop-up menu to assign or modify the value. The horizontal scrolling is available for HEADING and LEVEL but it is not available for SID values. The use of this menu is subjected to the Reclearance restrictions fully discussed in Chapter 3.

EFS Screen and Windows Description

2.3.1 EFS Windows Description The EFS Windows provide an environment for the EFS creation, cancellation, handling, and other functions typical in a Tower Control. There are three different types of windows displaying Electronic Flight Strips: Delivery Strips Window, Ground Strips Window and Tower Strips Window. The EFS Windows are opened from the EFS button displayed on the FDD. Each EFS Window can be divided into several working zones, separated by separation lines. Each EFS Windows displays a horizontal icon row (up, right under the “title bar”), which contains the Command Icons. The performance associated to each icon is fully described in further items of this section. Electronic Flight Strip roles can be adjusted in Tower Sectorization option in CMD position, allowing to group the roles (Delivery, Ground and Tower) in one or more positions (see CMD User Manual for details).

Figure 2-35: EFS Window – Ground and Tower roles in an unique position



Page 2-20



Figure 2-36: EFS Window Appearance and Elements (several working zones layout)

2.3.1.1 General Working Rules for EFS Windows Each operation and control procedure working with the EFS Windows is subject to the following points:



Page 2-21



MOVING EFSs

 An EFS is displayed in a working zone either manually (manual EFS generation or handed over action) or automatically (moved by the system from an EFS list).  When generated, an EFS is placed at the top of the working zone, above the separation lines. The new EFS is placed on top of the already existing EFSs. Exception is made: when clearing an EFS for take off while another already exists with “Line up and Hold” status. The new EFS is placed below the existing one in “Line up and Hold”.

DRAG STRIPS

 Dragging Strips is possible by left button pressing and hold, with the mouse’s pointer on the Call Sign field of the EFS.  A dragging action creates an “elastic vector” following the cursor movement while button is pressed, shown in Figure 2-37.  It is possible to drag strips:  Within a working zone.  From present working zone to next one (or to previous one). This operational step may also be achieved by clicking on the involved separation line or by clicking on the Clearance field (moves the EFS below the Runway line).  An EFS may be dragged back over separation line. The displayed symbols and FP information are updated according to the new EFS location.

MOVEMENT OF  It is possible for the operator to move the separation lines inside the corresponding SEPARATION LINES EFS Window, to increase or decrease a working zone according to traffic demands. This is performed by clicking on the diamond symbol displayed on the left side of the separation line and dragging the line until the desired position. While performing this action, the diamond-symbol color changes to RED.  The diamond symbol displayed on the left end of the separation as shown in Figure 2-37 is used for this purpose. When there are more flight strips to be displayed in a working zone than can be displayed, the top/ bottom half of the symbol on the separation line turns RED. The RED color indicates that the working zone above or below the line, respectively, is overflow. MANAGEMENT ADDITIONAL WINDOWS

OF  Additional Windows are included in each position. They can be opened and closed from icons situated in the bottom right hand corner of each position. Additional windows include:  CLD: Delivery pending window;  ARR: Tower pending window;  GND: Ground pending window;  BIN: Deleted strips window;  DE-ICE: De-ice strips window.



Page 2-22

Figure 2-38: Enlarged EFS Window (double)



Page 2-24



ENLARGEMENT OF  It is possible to enlarge (double) a window upon operator clicking on the arrowhead symbol displayed on the right end of the separation lines. An enlarged EFS Window is WINDOWS shown in Figure 2-38.  The icon column and row location mentioned above can not be modified. The icon column stays in the centerline of the doubled window.  The first working zone occupies the left half of the new window and the second one the right half.  The separation line, where the enlargement action was performed, is located at the top of the right part.  Upon enlargement, the necessary space of the screen is covered.  The System Control Window may be dragged aside if desired.  The return of a window to normal size is achieved by clicking on the same specific symbol used for enlargement.

2.3.1.2 EFS Delivery Window Description This window includes two areas, separated by the “Clearance received” separation line. Upper area includes the Delivery strips in notified status that have received the ATC clearance message, but are still on the DEL frequency. Lower area includes the Delivery strips in notified status that have not received the ATC clearance message yet.



Page 2-25



2.3.1.3 EFS Ground Window Description This window is divided in two areas by the “Runway” and “Taxi” separation lines. In the area defined below the “Taxi” separation line are displayed the strips added from the pending list.



Page 2-26



In the area defined above the “Taxi” separation line and below the “Runway” line are displayed the strips sent from the tower position.



Page 2-27



2.3.1.4 EFS Tower Window Description This window is divided in three areas by the “Taxi line”, “Runway line” and “Airborne line” separation lines. Arrivals will appear first in the top area of the list and drop as their status changes. Departures will first appear in the bottom area of the list and reach In the area defined between the “Runway line” and the “Taxi line” separation lines are displayed the strips sent from the ground position. In the upper area (below the “Airborne line” separation line) are displayed strips that are still airborne (approaching aircraft and that which received a “clear to land” clearance.



Page 2-28



2.3.1.5 Screens Layout and Roles Assignment The Default Windows layout set up in an ICW depends on the role(s) assigned to that position. The differences between layouts are the working zones available for each controller. The available zones are limited by separation lines.

2.3.2 List Windows This section describes all those windows displaying lists that manage Flight Plans for present or future processing. The information included in these lists is updated from the FDP and modified according to controllers operations during control session. In a normal working screen layout, a List Window can be located between EFS Outbound and Inbound Windows, since List Windows need a smaller space of the screen. EFS Lists Windows are opened or closed from MENU icon displayed in FDD main menu. .

2.3.2.1 Clearance Pending List Window Includes the flights that will be under control in ground list. It includes every strip whose flight plan has an SSR code assigned, in passive status, and appears a predefined time before its EOBT. As it becomes the notified status, it will be moved to EFS clearance window. Double click in the C/S field displays its flight plan. A strip can be moved from pending to Clearance list by Notifying it. To Notify one strip, double click in it, in pending window, and perform a notify action: select Notify bi-state icon and click in OK button.

3 EFS Operation In previous chapter, each element of the EFS Software (Windows, Strips, Obstruction Symbols, Menus, etc.,) has been described in order to provide a complete knowledge of the work environment supported by the system. Now, Chapter 3 contains a “step by step” description of the EFS operational procedures carrying out functions of ordinary tower control. These descriptions mention elements and objects that have been previously presented in Chapter 2. The included issues describing the operations for: Flight Plans, Electronic Flight Strips and Obstructions Symbols Management, different control phases according to the operator’s role, EFS transference and Handovers, Warnings presentations, and Coordination Window usage.

3.1

Electronic Flight Strips Management

Electronic Flight Strips appearance and fields were presented in Chapter 2. Besides this, in former sections were mentioned some operations not detailed yet and involving Flight Strips: Local Flight Strip and Strips Extension. Those operations are now described in present section.

3.1.1 Create, Modify and Cancel an Electronic Flight Strip for a Local Flight Local EFS (also called local flight plan) is a reduced FP created at the Tower System. Usually, it is a VFR FP, which normally does not exceed the tower jurisdiction, for instruction, testing or general purposes. Sometimes, the control of a Local Flight may be performed by ATCC. The controller is given the capability of creating a Local EFS from either the EFS Outbound or EFS Inbound Window by clicking on the “Local EFS” icon located on the upper icons row, as shown in next figure:

Figure 3-1: Local EFS icon The template has a format similar to the one of an empty expanded EFS but the Local EFS displays, by default, some fields (runway, time and departure/destination) and includes a couple of new icons:


INSERT

Inserts the new Local EFS

CANCEL

Cancels the operation

Figure 3-2: Local EFS Template The Local EFS Template counts on the following fields described with their filling up rules: ATIS VERSION

1. When clicking on this field, a horizontal scrollbar menu is displayed with selectable values for ATIS meteorological data version.

CALL SIGN

1. When clicking on this field, a pull down menu of pre-defined Call Signs is displayed. 2. When choosing a pre-defined Call Sign, the associated and pre-defined AC Type and Wake Turbulence are automatically inserted in those fields. 3. It is also possible to enter Call Sign using the keyboard. By selecting “-free-“ from the pull down menu, a window with three fields (Call Sign, Aircraft Type and Wake Turbulence) is displayed to enter the values from the keyboard. 4. The values on this field can be modified by clicking with the LEFT mouse button on it. Then, a window with the current value is displayed to allow the controller the modification of the value. Syntax validation is available for Wake Turbulence field being only possible the L, M or H characters.

WAKE 1. If not defined yet by associated data to a pre-defined Call Sign, it is also possible to enter them through the keyboard (see Call Sign field above). 2. For Modification procedure see Call Sign field above. 3. If a free text enter is carried out in the expanded Local EFS, a “frame” is displayed surrounding the field. 1. Clicking with the LEFT mouse button, a pull down menu is displayed to allow the controller to enter or remove the deice mark and the holding points valid for the selected runway. This action can be performed only when the Local EFS has been created.


Page 3-2



DEPARTURE/DESTINATION

1. By default, when it is an outbound flight strip, the value displayed in the field is the Destination airport and, when it is an inbound flight, the displayed value is the Departure airport. 2. It is possible to fill the Destination Aerodrome field for Outbound flights, and the Departure Aerodrome for Inbound flights using the keyboard but only while the Local EFS is being created. It is performed by clicking on the field with the LEFT mouse button, displaying a window to enter the value.

SID / STAR

1. For Local EFS, the SID field contains an identifier of a local VFR route. 2. Clicking with the LEFT mouse button opens a pull down menu of VFR routes (only for the outbound local EFS). 3. As all local flights are VFR, a “frame” is displayed surrounding the field.

RUNWAY

1. It opens a pull down menu of possible runways. 2. By default, the runway field is the default take off runway for outbound flights, and the default-landing runway for inbound flights.

TIME

1. Possible displays of this field:  Estimated Off-Block Time (EOBT), for outbound flights.  Estimated Time of Arrival (ETA) for inbound flights. 2. After changing the time, the color also changes. This is not applicable when the Local EFS is being created. 3. By default, the time is set to the current time of the ICW.

FREE TEXT

1. It is possible to enter Free Text information in the expanded EFS.

SSR Code

1. Upon Local EFS creation, the FDP assigns a local SSR code to that flight. It is displayed on the expanded EFS when inserted.

By pressing on the “INSERT” icon, the data entered by the operator are sent for validation. Completed the validation, an Expanded EFS is created on top of the EFS Outbound Window, if it is a departing aircraft; or in the EFS Inbound Window, if arriving. The Local EFS are distinguishable from the normal Full FP EFSs through color attributes, since they are displayed in light YELLOW.

Runway Management

3.7.1 Runway closing and reopening Click on the affected Runway icon (located at the top of the EFS Outbound and Inbound Windows). It changes from open status (green colored) to closed, and the icon turns to RED. The same color change is carried out in the associated runway lines.



Page 3-8



Figure 3-15: Closing a Runway The runway status change, closing and reopening, are subjected to these rules: 1. The icons and lines color changes are carried out at the ICW controlling the corresponding runway. 2. Each outbound EFS allocated for taking off on the closed runway is displayed with a large RED “X” in the Clearance Field. The RED X is displayed and combined with other symbols previously presented, except the “line up and hold”, which is removed. 3. Each inbound EFS allocated to that runway also has the RED “X” in the Clearance Field. 4. It is possible to move outbound EFS across the RUNWAY LINE although the runway is closed. In this case, the RED X is not deleted from the Clearance Field until the runway is opened again. Electr onic Flight Strip User Manual

Departure Flight Control Procedures

3.8.1 Clearance Delivery Procedure This is the basic operation assigned to the CLD position. The Clearance Delivery operation follows these steps (see Figure 3-16): 1. The Flight Plan data are displayed at the CLD Pending List a certain VSP time before EOBT or CTOT, if the EOBT/CTOT exist. 2. When the pilot is requesting “Clearance”, the controller activates the FP by clicking, with the LEFT button, on the ACT field of the corresponding line in the CLD Pending List. Then, an active EFS (white) is generated in the “Active Working Zone”, above the TAXI LINE as an expanded EFS and the SSR Code is also allocated.

3.8.1.1 Change to Taxi state It can be done by dragging the EFS across the TAXI line, or performing a handover action.

3.8.2.3 Change to “Line up and Hold” state The change to “Line up and Hold” is performed by dragging the EFS across the RUNWAY LINE or directly clicking on this line. The EFS nearest above the runway line is the one to move if clicking on the line. A “Line up and Hold” symbol, RED “=“, is displayed at the Clearance Box in that moment.

3.8.2.4 Change to Take off state The TWR controller can deliver clearance for Take off directly from Taxi status by clicking on the Clearance Field of the EFS. The EFS is, then, automatically moved across the Runway line, and a GREEN up arrow is displayed on the Clearance Field. If the EFS is in “Line up and Hold” status, the change to “Take off” status is done by clicking on the Clearance Field. Any EFS cleared for take off coming from the taxi phase is displayed below all the EFSs in “Line up and Hold” status.

3.8.2.5 Putting an Aircraft back to Taxi state In order to change an aircraft back to Taxi status, its EFS is dragged upwards across the RUNWAY LINE. This action causes any symbol displayed in the Clearance field to be deleted.

3.8.2.6 Putting a Cleared for Take off Aircraft back to Line up and Hold status A new click on the Clearance field is understood as a “Cancel Take off” action and restores the RED “=“. This action is not allowed if the ATD has already been inserted either manually or automatically.

3.8.2.7 Transition to Departure state Once the Radar has detected the aircraft, the flight is considered airborne. In that moment, the ATD is inserted automatically in the Time field and displayed in GREEN background color, substituting the EOBT or CTOT. Besides this, it is possible to insert ATD manually.

3.8.3 Modifications of an Departure EFS for an “Ad-hoc Clearance” Controllers are allowed to propose changes in a Departure EFS relative to:  SID  Level  SID and Level Electr onic Flight Strip User Manual


Page 3-12



 Heading and Level  Runway  Time (Whenever the flight is in Take-off or further states) The above mentioned changes can be performed as described in the following items. Changes are subject to these rules: 1. The controller is allowed to change the Level without changing the Heading but a change in Heading must be accompanied with a change in the Level. This action is functionally carried out by pull down menus. 2. A change in Heading and Level replaces the existing SID.

3.8.3.1 Changing SID Clicking on the SID field of the Departure EFS, a pull down menu is displayed listing all the available SIDs for allocated runway. This is shown in below figure:

Figure 3-18: SID Pull Down Menu

3.8.3.2 Changing Level The controller is allowed to specify a non-standard climb out through the pop-up menu available by clicking on the GATE/RECLEARANCE field. This menu is shown in following figure:



Page 3-13



Figure 3-19: Reclearance Pop-up Menu This menu is divided into three different submenus: SID, HEADING, and LEVEL. To close this menu without selecting a value, click on the title bar of any of the different submenus SID, HEADING or LEVEL.

3.8.3.3 Changing SID and Level If a change in both values is desired, click on the Gate/Reclearance field and choose both of them from the pop-up menu shown in former figure.

3.8.3.4 Changing Heading and Level It can be performed from the same pop-up menu as the former operation. The new heading is displayed on the SID field (instead of the SID previously displayed), and the new level is displayed on the Gate field.

3.8.3.5 Changing Runway It can be performed by clicking on the Runway field and select a new runway from the pull down menu. Changing the Runway causes an automatic change of the SID.

Figure 3-20: Runway Pop-up Menu

3.8.3.6 Changing Times This change can be manually performed, to enter different time values for first fields in extended strip first line. Each time is entered once, by LB clicking in TIMES field; after each acceptance, its background changes. Next LB click in TIMES field will be for setting the next time value. The Times to be set in this field, in the correct order:  Start Time (background in WHITE); 

Push Back Time (background in LIGHT GREEN);

Figure 3-22: Times Modification

3.8.4 Changing Time It is possible, when the flight is in states previous to Take-off, to acknowledge the CTOT whenever it is performed from positions with a role different from RA or RB. This is done by clicking with the left mouse button in the Time field whenever the time shown on it is the new or revised CTOT. When acknowledging the CTOT, the background colour will change from background colour to Green as shown in the figures below:

Tower Flights Control Procedures

3.9.1 Pending EFS State The EFS in Pending EFS state is displayed in the Tower pending list: 1. Flights will automatically be displayed a VSP time before the Estimated Time of Arrival (ETA). Electr onic Flight Strip User Manual


Page 3-15



2. A flight may be manually moved from Tower Pending List to Radio Contact Zone by clicking with the LEFT mouse button on the ACT field.

Figure 3-24: Tower EFS Window

3.9.1.1 Cleared to Land State The zone under the RUNWAY is named in this manual as “Clear to Land” working zone. When giving “Clear to Land” to the aircraft, the Tower controller can move the EFS in three different ways to enter the “Clear to Land” state:  Dragging the EFS across RUNWAY LINE.  Clicking on RUNWAY LINE, moves the closest EFS above the line.  Clicking on EFS Clearance Box.



Page 3-16



Any of the former commands causes the EFS to be displayed below the RUNWAY LINE and a GREEN down arrow is displayed on the Clearance field.

3.9.2 Landing Aircraft Control This includes all control procedures from clearance to land until the flight is terminated at gate. During this phase, the following commands are available: Go Around, Manual ATA. General control commands are however available for this phase: Dragging EFSs, C/S Highlighting.

3.9.2.1 Missed Approach: Go Around Command If an arrival flight is executing a Missed Approach, this is processed by pressing the RIGHT mouse button on the Clearance field. This input will initiate the following action: 1. A RED up arrow substitutes the previous GREEN down arrow in Clearance field.

Figure 3-25: Symbol change in Clearance field 2. STAR and GATE information will be replaced by “MIS” and “IFR” key words, both in black characters. 3. If an IFR clearance is required, new Heading and Level can be entered from the pop-up menu available upon click on the GATE field. New data entered are displayed in YELLOW. The new heading will be displayed in the STAR field and the new level in the Gate field. 4. New landing attempt can be started putting the EFS back to Radio Contact Zone, simply by dragging the EFS upwards across the RUNWAY LINE. With this action, the RED arrow is deleted leaving the Clearance field blank. However, “MIS” and “IFR” (or the new Heading and Level, if entered), are not removed. 5. Ready to land again, the operation follows as usual. Drag the strip downward across the RUNWAY LINE to put it to Clear to Land Zone. The original STAR and GATE information is restored in the corresponding fields.

Page 3-17



3.9.2.2 Arrived State When ATA is automatically displayed in the Time field based on Radar detection, the flight is changed to Arrived state. The ATA is displayed in GREEN background color and the previous GREEN down arrow is cleared from the Clearance field. It is also possible to enter the ATA manually through the pop-up menu available by clicking on the Time field. It is possible for the controller to indicate the exit of the arrived flight through any exit way. This action is performed by choosing one of the available intersection points of the pull down menu associated to the Taxiway field. Taxi State When the EFS is moved downwards, across the TAXI LINE, it is entering the Taxi state.

3.10 Flight Plan Handover functions (intra Tower) This section provides a description of each FP handover process that can be carried out between controllers by means of the EFS system. Available commands for this function are:  Quick Handover  Vertical Line These Handover procedures are fully described in following subsections. This terminology is used, with the enclosed meanings: “Giving” controller: is the operator controlling the flight. His/her ICW is currently displaying the EFS associated to the flight pretended for handing over. “Receiving” controller: is the controller taking over the responsibility for the flight. Once the handover process is completed, his/her ICW displays the transferred EFS. The Quick Handover procedure does not require coordination between the giving and receiving controller. In this case, no action is required nor allowed by the receiving controller to accept or reject the handover. However, the Vertical Line procedure requires coordination between the giving and receiving controllers. The Obstruction Symbols can be transferred between the controllers in the same manner.

3.10.1 Quick Handover For this procedure, the giving controller has to drag the EFS to the icon associated with the desired receiving controller. No acceptance from receiving controller needs to be given. The handed over EFS is deleted from the giving controller screen, and displayed at the receiving controller. NOTE: For an Arrival EFS above the Runway line and for a Departure EFS below the Runway line, when the controller initiates a Quick Handover, it will be treated as a Vertical Line Handover. That is, after initiation (clicking with the LEFT mouse button on the Call Sign and dragging to the receiving controller icon):  Vertical Line appears to the left of the Call Sign on the EFS.  

The Vertical Line appears on both giving and receiving controller’s displays. The receiving controller needs to acknowledge the handover.



Page 3-18



Figure 3-27: Quick Handover

3.10.2 Vertical line This Handover mode is only possible if the working zone, from where the “giving” controller is initiating the handover, is also an available zone for the role where the EFS must be transferred.



Page 3-19



This procedure requires acceptance, from receiving controller. It is started by the giving controller, clicking on the desired receiving controller icon, and moving the “elastic vector” to the Call Sign field of the EFS to be handed over.

Figure 3-28: Handover process (Vertical line - Start)



Page 3-20



A colored sensitive Vertical Line is generated on the left of the Call Sign. An identical EFS is displayed at the same working zone, on the receiving controller’s screen. This duplicate EFS is shaded and has the same Vertical line in the Call Sign field.

Figure 3-29: Handover process (Vertical line)



Page 3-21



The receiving controller can accept the transference by LEFT button clicking on the line. This action successfully completes the handover process. Shading and the vertical line are cleared and EFS is deleted from giving screen. When the EFS is presented in both controller positions, the handover process is able to be cancelled, by either the “Giving” or “Receiving” controller, by clicking with the RIGHT button on the sensitive vertical line. Doing this operation the shaded EFS is removed from the “Receiving” controller screen and the vertical line from the EFS on the “Giving” controller screen.
