Product Description

AR-SERIES DESIGN OVERVIEW

All AR-Series Recorders are of non-ARINC form factor in order to minim ize the total installation cost and weight. In addition the Pre-amplification and Signal Conditioning functions of the Microphone Monitor (Control unit) have been incorporated within the recorder Chassis, which includes three (3) Shop Replaceable Units (SRU's), as depicted in Figure 3: ♦

Interface and Controller Board (ICB)

♦

28Vdc Power Supply (PS)

♦

Crash Survivable Memory Unit (CSMU)

The AR-Series Recorders utilize a small, lightweight, modular crash survivable memory unit (CSMU) for protection of the solid state memory. State of the art high-density FLASH memory devices are combined with the use of mature industry standard audio digitization and encoding integrated circuits (ICs). The CSMU may be removed from its mounting shelf by simply removing four bolts and releasing its mating connector. In addition to the described SRUs, an Underwater Locating Beacon (ULB) is attached to the CSMU by four (4) mounting, to avoid separation in the event of an incident. The mounting of the ULB also facilitates easy access for replacement of its battery. Crash Survivable Memory Unit (CSMU)

Product Description

No scheduled periodic maintenance or servicing is required during the life of AR products (except for the TSO C121 approved ULB, which requires battery replacement approximately every 6 years). The AR series has been designed to detect and isolate errors to the Shop Replaceable Unit (SRU) level, and its modular fashion allows SRU replacement for ease of repair with an estimated Mean Time to Repair (MTTR) of 30 minutes.

A key element of the AR-Series design is that the audio recording uses an industry standard encoding method (G.723 CCITT, 24kbs). This approach provides several advantages to the user: •

The audio digitization and encoding have been matured through widespread use in consumer equipment, and in current Honeywell SSCVR units.

•

The encoding algorithm is extensively used in personal computer based high quality audio systems, thus decoding/playback tools are inexpensive and commercially available .

The audio circuits, digitization/compression process, and memory resolution meet the improved audio performance requirements of ED-56a, thereby assuring the highest level of audio recording fidelity. FDR/DVDR Data recording is accomplished in the same manner as previous Honeywell Solid State FDRs, that is, without data synchronization or compression, thereby providing several advantages to the user: •

The equipment will work identically without regard to special FDAU sync patterns.

•

Maintenance and troubleshooting of complex compression algorithms are avoided.

•

Recording duration does not vary with aircraft flight profile, nor is a specific aircraft database required.

The flight data input circuits meet ARINC-717/747 interface requirements with the FDAU and Mil-Std-1553 redundant buss requirements.

The superior performance of the CSMU is the result of 45 years experience with designing and producing protective enclosures !

Impact shock of 3400Gs

!

500 lbs. dropped from 10 feet

!

High temperature fire exposure in excess of 60 minutes

!

Low temperature fire exposure of 260 oC for a period of 10 hours

!

Deep water immersion at a depth of 20,000 feet for a period of 30 days

!

Salt water immersion at a depth of 10 feet for a period of 30 days

As shown in Figure 6, a very simple package design has been achieved, which not only contributes to its industry leading survivability characteristics, but also assures a high degree of maintainability.

The CSMU is easily removed from the top of the AR-Series chassis without having to disassemble the remainder of the unit. The CSMU uses modular "dry-block" materials for both the insulating liner and thermal mass, there is no need to deal with the sticky thermal jells or special insulating fluids.

REMOTE AREA Microphone Design Overview

In order to reduce weight and cockpit panel space requirements the AR-Series recorders have incorporated the Pre-amplification and Signal Conditioning functions of the Microphone Monitor (Control unit) within the recorder chassis. Therefore the optional Erase, Test, Headphone and Status functions may be provided on a separate Status Panel, at the installers’ discretion. The area microphone, which meets the requirements of ED-56A and TSO C-123a, is a small device intended for location in the cockpit am bient audio environment, and is provided with f lying leads, as shown in Figure 7.

AR-SERIES SYSTEM SUPPORT EQUIPMENT

The same family of Ground Support Equipment as their Air Transport predecessors (the SSCVR and SSFDR) supports the AR-Series recorders.

Playback and Test Station (PATS) The PATS is a PC-based workstation which includes Windows ®-based acceptance test, return-to-service and diagnostic software for the AR-CVR, AR-FDR, AR-DVDR and SSCVR. Full audio playback of all recorded information is provided, including data display of the optional Rotor Speed indication. The PATS is configured with a GBE Interface Board containing the high speed RS-422, discrete interfaces, ARINC-429, and Mil-Std-1553 interface channels necessary to test the AR-Series functions. The PATS also contains up to 3 commercial dual-channel digital-audio boards. These are used for audio input/output during CVR audio tests, and for audio output (to speakers) during playback. Since the "TEST" function does not preserve the data contained in the recording memory, the PATS operations are segmented into two distinct applications; "Playback" and "TEST". This provides a level of protection against unintentional erasure or re-write of recorded audio.

Product Description

AR-SERIES INSTALLATION RECOMMENDATIONS

MECHANICAL INSTALLATION The Honeywell Solid State Advanced Recorder (AR) family was designed specifically for use in weight sensitive aircraft and helicopters and has the following installation advantages over standard Recorders • small, • lightweight • no mounting rack required • no cooling required • may be mounted in any orientation • cockpit mounted control panel not required • Status panel optional .

The AR-Series is sufficiently robust that it may be hard mounted (i.e. a shock/vibration isolation tray is not required) in any orientation . This, combined with the small form factor, allows more latitude in mounting location on the aircraft. AUDIO INTERFACE The area microphone, part number 980-6113-010, is a small device intended for location in the cockpit ambient audio environment, and is provided with flying leads. This is a pre-amplified device and allows for a greater distance from the Microphone to the AR-Series Recorders. The Area Microphone is installed using a bracket screwset and requires a simple mounting bracket, which may be manufactured by the installer. DATA INTERFACE The AR-Series data recording is in accordance with ARINC-573/717, ARINC-429, or Mil-Std-1553 and can be interfaced to a Flight Data Acquisition Unit (FDAU). STATUS PANEL In order to reduce weight and cockpit panel space requirements the AR-Series recorders have incorporated the Pre-amplification and Signal Conditioning functions of the Microphone Monitor (Control unit) within the AR-Series chassis. Therefore the optional Erase, Test, Headphone and Status functions may be provided on a separate Status Panel, at the installers’ discretion.

To minimize the cockpit real estate requirements it is recommended that the operator design (per space requirements) a panel that includes CVR and FDR Fault Status lamps as well as a Headset jack. FAULT and STAUS INDICATIONS The AR-Series Recorders provide the following outputs to an optional cockpit indicator. CVR MAINTENANCE FAULT OUTPUT This output is normally short circuited (using a relay) to chassis ground (500 mA max, 1 VDC max), but if any CVR section(s) of the DVDR malfunction, if the DVDR is removed from the aircraft, or if the system power is off, this output will toggle to an "open" state (>100,000 ohms). FDR MAINTENANCE FAULT OUTPUT This output is normally short circuited (using a relay) to chassis ground (500 mA max, 1 VDC max), but if any FDR section(s) of the DVDR malfunction, this output will toggle to an "open" state (>100,000 ohms). FDR STATUS OUTPUT When the DVDR is functioning properly, the FDR Status output is in an "open" state (>100,000 ohms). If an internal FDR related error occurs, the output will toggle t o chassis ground (500 mA max, 1 VDC max).
