Can aircraft fly without black box?

“Black box” recording and storage equipment are compulsory on all commercial and corporate flights. The black box is actually two separate pieces of equipment - a cockpit voice recorder (CVR) and a flight data recorder (FDR). These record and store all audio, flight control info, and other data throughout the flight.

However, each ELT is specifically designed for each aircraft, so it cannot be tampered with. You also cannot turn off the black box, as it runs throughout the flight, recording every 30 to 60 seconds.

To record data in extreme situations, the black boxes resist extreme temperatures in case of fire and being submerged as deep as 6,000 metres into the water. > In case the plane crashes into the water, an underwater beacon will send out pulses which can be detected by an audio equipment.
