After the events of Malaysia, we thought about how the so-called Black Box works on each plane.
A "black box" is an electronic device, which is built to record the data that occurs during duration μίας αεροπορικής πτήσης. Μια μονάδα black box αποτελείται από 2 τμήματα: το CVR (Cockpit Voice Recorder) και το 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 to analyze safety issues during a flight, and in case 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 at the tail of the aircraft because it has been found to be the safest place. It withstands very high temperatureswinees (1.100 degrees Celsius for 1 hour or in temperature 250 degrees Celsius for 10 hours). It withstands the pressure of a depth of 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.
All of the above is described in the Associated Press video
