Flight Data Recorder
|Term||Flight Data Recorder|
Cockpit Voice Recorder (CVR)
device used to record specific aircraft performance parameters.
The purpose of a FDR system is to collect and record data from a variety of airplane sensors onto a medium designed to survive an accident.
Flight recorders comprise two systems, a flight data recorder (FDR) and a cockpit voice recorder (CVR). Sometimes, both FDR and CVR functions are combined into a single unit (ICAO Definition: Combination recorders). Combination recorders need to meet the flight recorder equipage requirements as specifically indicated in ICAO Annex 6 – Operation of Aircraft. (Note source: Skybrary)
