Aircraft flight data recorder

SENTRY FDR is the flight data recorder in the Flight Data Systems SENTRY family. It captures the parameter set your authority requires, in a titanium enclosure small enough for installations that will not accept a conventional recorder.

Built for the bay that has no room left

• Flange mounted without a mounting tray, in any attitude
• Adapter tray available where the bay was sized for a larger legacy unit
• Same envelope and weight as every other SENTRY configuration

Parameter capture across mixed avionics

• ARINC-717 input at 64, 128, 256, 512 or 1,024 WPS, automatic bus rate detection
• Sync on ARINC-717 or 573, forward or backward
• ARINC-717 echo out for downstream equipment

Product numbers
FDS84-1000 and FDS84-1001, SENTRY Flight Data Recorder

FPGA architecture, SWaP optimized

• FPGA-based architecture with SWaP optimization, tailored for modern airframes
• Reduced footprint and low mass support direct replacement of legacy recorders without introducing new aircraft constraints
• Lower steady-state power draw preserves electrical margin for mission and cabin loads
• Contains no software, so recording is licence-free and no proprietary software is needed to retrieve the data
• Optional safety-critical soft-core processor available for third-party software

Specifications

• 3.3 in H x 4.9 in D x 6.0 in W (85 x 124 x 152 mm), base recorder
• 4.5 lb (2.04 kg), titanium enclosure
• 28 V DC, 4.5 W nominal
• Crash survivable to EUROCAE ED-112A
• Patent-pending memory protection system

Interfaces

• Ethernet 10/100 Base-T
• ARINC-717, 64 to 1,024 WPS
• ARINC-429, minimum two inputs
• RS-422/485
• Analog and discrete sensor inputs
• Two rotor speed inputs
• Four audio inputs, high or low fidelity

Certification

• TSO-C124c Flight Data Recorder Equipment
• Meets the requirements of EUROCAE ED-112A
• Qualified to DO-160G
• Installation approvals are published in the Flight Data Systems STC library

Ready for FOQA, not just the investigation

• Fast download over the GSE connector using HHMPI, no recorder removal
• Reserved storage for Flight Recorder Electronic Documentation to ARINC 647A

Installation notes

• Operates on a valid ARINC-717 stream from the aircraft's flight data acquisition unit
• Where no suitable source exists, or outputs do not match, an FDS Modular Acquisition Unit can format data upstream to ARINC 429 or ARINC 717
• Beacon position and the optional RIPS module change the installed envelope. Regional beacon requirements apply, including Canada's mandate for non-lithium Underwater Locator Beacons
