The tragic crash of an Air India Boeing 787-8 in Ahmedabad highlights the vital role of black boxes in aviation investigations.
Australian scientist David Warren came up with the idea for the cockpit voice recorder after investigating the crash of the world's first commercial jet airliner, the Comet, in 1953.
A black box comprises two parts:
Cockpit Voice Recorder (CVR): Records radio transmissions, pilot voices, and engine sounds, crucial for understanding crew communications and ambient noise.
Flight Data Recorder (FDR): Monitors at least 88 parameters (like altitude, airspeed, heading) in new planes, potentially over 1,000, allowing for computer-animated flight reconstruction.
Note: Helicopters are equipped with a (single) combined recorder, capable of recording all the data needed to characterise the flight (time, heading, altitude, power, temperature, rotor speed, outside temperature, etc.).
