After the events of Malaysia, we thought about how the so-called Black Box works on each plane.
The "black box" or "black box" is an electronic device, which is built to record the data that occurs during an air flight. A black box unit consists of 2 parts: the CVR (Cockpit Voice Recorder) and the FDR (Flight Data Recorder).
The VAT no., records everything that happens in the cockpit, such as the conversations with the control tower, the conversations of the pilots in the cockpit, engine noises, flight weather reports, and more. It has autonomy two hours – after this time it starts again from the beginning and continues recording from where it left off.
The FDR, records all aircraft behavior during the flight.
The data recorded in the "black box" is used for analysis safety issues during a flight, and in the event of an accident to investigate the causes.
It is called a "black box" but it is not black. It is orange to be easily detected in case of a plane crash and much more if it has fallen into the sea.
It is placed in the tail of the aircraft because it has been found to be the safest point. It can withstand very high temperatures (1.100 degrees Celsius for 1 hour or 250 temperature Celsius for 10 hours). It withstands the depth pressure up to 6.000 meters.
A special transmitter that is placed in the "black box" as soon as it comes in contact with water, begins to emit a signal that can be detected at a depth of up to 5.000 meters.
