In any plane, commercial or private, must be on-board voice recorder and trip recorder. These are two separate devices, but we usually call the two "black box».

All recorders are many tests, including exposure to 1110 ° C for one hour and 260 ° C for ten hours. The devices are capable of operating at temperatures from -55 ° to + 70 ° C, and they can record up to 25 hours of flight. They can also make a lot of pressure throughout the 30 days, if you will be in deep water.





When the June 1, 2009-the year in the Atlantic fell plane Air France Flight 447, all 228 passengers and the entire crew were killed. No one knew what really happened until nearly two years later, in May of 2011, all the black boxes of the aircraft did not get to the ocean floor.



Surprisingly, the black boxes are still working, despite the pressure and sea water for two years. Records showed that the accident occurred not because of mechanical failure, or severe weather: the crew raised the nose of the aircraft, the airspeed decreased, but to return the aircraft to its normal position did not happen, and the plane crashed into the ocean.
