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 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 conversations with the tower control, τις συνομιλίες των πιλότων στο πιλοτήριο, θορύβους της μηχανής, μετεωρολογικά δελτία πτήσης, και άλλα. Έχει αυτονομία δύο ωρών – μετά από αυτό το χρονικό space it starts again from the beginning and continues recording from where it stopped.
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 temperatures (1.100 degrees Celsius for 1 hour or at a temperature of 250 degrees Celsius for 10 hours). It withstands pressure depths 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
