FLIGHT RECORDER


Meaning of FLIGHT RECORDER in English

Instrument that records the performance and condition of an aircraft in flight.

Regulatory agencies require these devices on commercial aircraft to make possible the analysis of crashes or other unusual occurrences. They are housed in heavy steel within layers of insulation, protecting them against impacts and fires. The recording tape is also protected against inadvertent erasure and contact with seawater. It records airspeed, altitude, heading, vertical acceleration, and aircraft pitch. It also includes a separate device that records voice communication within the aircraft and by radio. Both recorders are carried in the tail of the aircraft.
