A flight recorder is generally known as black box. It is an electronic recording device which is placed in an airplane and is used for the investigation of aviation accidents and other incidents. Presently it is available in orange in color.
Dr. David Warren was the first Australian scientist who invented the black box. The Australian scientist was working at the Aeronautical Research Laboratory in Melbourne in the mid-1950s and he was involved for the examination of the mysterious accidents in the world’s first jet-powered commercial aircraft. It is useful for investigators in which the examinations of the recording for happening in the final moments before the airplane accident then he got to work on a basic flight data recorder.
Australia became the first country in the world to make the Black Box compulsory for all commercial aircraft.
Flight Data Recorder (FDR):
It is a device that saves the recent history of the flight by the recording of dozens of limitations collected several times per second.
Cockpit Voice Recorder (CVR):
It is a device which preserves the current history of the sounds in the cockpit including the conversations between the pilots. The two recorders give accurate evidence, narrating the aircraft's flight history for help in any later investigation.
The FDR and CVR may be combined in a single unit. The two recorders are essential for the international guideline which is supervised by the International Civil Aviation Organization, for the conditions likely to be encountered in a severe airplane accident. Due to this reason, they are typically specified to withstand a consequence of 3400 g and temperatures of over 1,000 °C (1,830 °F) as required by EUROCAE ED-112 and have been essential in commercial aircraft in the US since 1967.
