Aircraft flight data recorder CVFDR

SENTRY CVFDR combines cockpit voice, flight data and data link recording in a single ED-112A unit. For operators carrying two separate recorders today, it removes a box, its mount, its wiring and its weight.

One unit where two used to go

• Combined function in the same envelope and the same 4.5 lb as the single-function units
• On weight-critical platforms, the difference against a two-box installation is the argument

Three recording functions, three TSOs

• TSO-C123c voice, TSO-C124c flight data, TSO-C177a data link, in one line replaceable unit
• Independent fault annunciation per function on separate discrete outputs

Optional independent power

• RIPS maintains recorder and cockpit area microphone for 10 minutes after loss of aircraft power
• Yearly serviceability check, performed with an HHMPI or equivalent

Recording duration

• 2 hours of audio, minimum 2 hours of data link
• Operators requiring 25-hour cockpit voice recording should see SENTRY25, same enclosure, service bulletin upgrade path

Product numbers

• FDS84-3000 and FDS84-3001, SENTRY CVFDR
• FDS84-3100 and FDS84-3101, SENTRY CVFDR with RIPS
• FDS84-4300 Cockpit Control Unit for CVR and FDR installations
• FDS84-5001 Cockpit Area Microphone

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-C123c, TSO-C124c and TSO-C177a
• RIPS configurations add TSO-C155b
• Meets the requirements of EUROCAE ED-112A
• Qualified to DO-160G
• Installation approvals are published in the Flight Data Systems STC library

Installation note

• Flight data function 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
• 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
