Description

Flight Data Recorder (FDR) - device used to record specific aircraft performance parameters. The purpose of an FDR is to collect and record data from a variety of aircraft sensors onto a medium designed to survive an accident.

An FDR has historically been one of two types of "flight recorder" carried on aircraft, the other being a cockpit voice recorder (CVR). Where both types of recorder are fitted, they are now sometimes combined into a single unit (ICAO Definition: Combination recorders). Combination recorders need to meet the flight recorder equipage requirements as specifically detailed in ICAO Annex 6 - Operation of Aircraft.
