The DFIRS 2100 is a combined flight data recorder (FDR), cockpit voice recorder (CVR) and emergency locator transmitter (ELT) designed to provide instantaneous alert and accurate location of a downed aircraft, assist in the speedy rescue of survivors, aid in the recovery of the aircraft and assure timely recovery of vital accident investigation data.
In the event of an accident, the beacon airfoil unit is automatically triggered by on-board sensors, launching it from the platform, and emitting a distress signal as well as the aircraft’s last-known latitude and longitude. From there, it floats indefinitely, making it easier for rescuers to find survivors quickly.
The Combined CVR, FDR and ELT is used in a deployable, crash-survivable airfoil that can be installed on helicopters, fixed-wing and fast-jet aircraft.
In order to meet current and expected future avionics recording requirements, the AMU acquires and processes a diverse mix of signals and supports several digital I/O formats including MIL-STD-1553B, ARINC-429, ARINC-717 and high-speed RS-22. The AMU can also output data to multiple recording devices for dual-combined recorder installations.
The AMU is modular in design and can be configured and upgraded as needed. A maintenance port provides the ability to upload new application software, new configuration tables, exceedance monitoring software, view the maintenance log and run test software. Its unique signal acquisition software allows data I/O processing to be customized to meet the specific needs of the operator, without any need for special interface cards. The user can also set up additional events to monitor avionics, engines, fuel flow and other dynamic and structural components.
