The Sentry Cockpit Voice & Flight Data Recorder (CVFDR) was designed by combining the standard features of existing CVFDRs with a new approach to capturing and protecting flight data creating the foremost CVFDR of the future.
Using a patent-pending innovative memory insulation technique Sentry offers small size, lower weight, and less power consumption than traditional CVFDRs in a modular and flexible architecture.
The “software free” recorder allows for aircraft specific configurations as well as the addition of creative and useful expansion capabilities.
Available in stainless steel or titanium, Sentry meets or exceed all requirements of ED-112A as well as qualification to DO-160G and MIL-STDs-461, 810, and 704 environmental and power requirements.
The rugged enclosure is ideal for airborne operational environments including commercial and military fixed-wing and rotary wing aircraft and can be mounted in any attitude.
Sentry Includes a range of aircraft interfaces including:
ARINC-717 and ARINC-429 (auto detection)
MIL-STD-1553 • RS-422/485
Analog and discrete sensor inputs
Data Link recording
Four high or low fidelity audio channels (configurable)
Rotor speed input
Expansion of Sentry’s capabilities includes the acquisition modules designed for the FDS Modular Acquisition Unit (MAU).
The modules convert Sentry into a Data Acquisition and Crash Recorder System and more:
Expanded Data Acquisition with ARINC 717 and 429 output − ARINC 717, ARINC 429 and MIL-STD-1553 inputs − Analog/Discrete inputs
