The black box contains all the contents and data before the plane accident. Finding the black box means finding the truth about the plane accident. The black clip is equivalent to the driving recorder on the car. Its scientific name is actually aviation flight recorder, which can restore and let us know the information before the accident. As for why he was called the black box, it was because all kinds of electronic instruments of early airplanes were stored in a black square box. Later, after continuous innovation and invention, the black box has been habitually called the black box.

The appearance of a black box is actually not black but conspicuous orange, and it is not like a box, but a combination of a cylinder and a cuboid. The black box plays a great role in the plane, which is mainly composed of two parts, namely the cockpit voice recorder and the flight data recorder. Don't underestimate this black clip, it can record the conversation between the pilot and the ground, the conversation of the pilot, and even the sound of the aircraft engine, as well as the flight speed, flight trajectory, resistance and so on. Can be accurately recorded. These data are very important for aircraft with safety accidents. How to quickly find the problem of the plane according to the black box and trace the cause of the accident?

Usually, when an airplane has a safety accident, the black box can be well preserved, which is due to the importance of the black box in the airplane. Because of its existence, people can discover the truth of the accident, so the black box is strictly screened in materials and storage locations. Aircraft are usually placed in the tail, and its material is a very hard steel, which can withstand two tons of pressure for five minutes without damage. Not only that, it also has the functions of high temperature resistance, waterproof and corrosion resistance. Now, I can only pray for the people on the plane and pray for them.
