Black Box Video

The phrase "black box" means a device, which is important for the final result, not its internal structure. This term is often called the flight recorders of the aircraft.

Seeing a black box for the first time, many will think that they have been deceived. And, in fact - is a round device is red or orange may be a black box? Can and how! The round shape of the body of the recorder is able to withstand enormous loads, and bright color is needed to facilitate the search for the device.

Flight information in a black box is fixed to a magnetic tape or flash memory. In the very first recorders, wire was used to record information. The internal device of the recorder is almost like any other recording device, be it a tape recorder, a dictaphone, etc. The uniqueness of the black boxes is in their case. Since the main task of the boxes is the safety of information, the black box case is made of titanium and heavy-duty steel, and inside it is covered with heat-insulating material. This allows you to withstand truly titanic loads (overloads in 3400 G, diving at 6 km under water and even fire up to 30 minutes).

To facilitate the search recorders equipped with ultrasonic beacon is automatically activated when immersed in water. The signal at a frequency of kilohertz can be 37,5 zapelengovan search group, and then the detection of the box becomes a fairly simple task. Find the black box on the ground is also quite simple to find the wreckage of the aircraft and armed with knowledge about its internal structure.

Flight data recorder can detect most of the tail of the aircraft, which are statistically less likely to damage when exposed to air crashes. But it will be only one of several recorders - because all the systems on board the aircraft are duplicated, and sometimes - and more than once. So it does not exclude the possibility to discover a black box.

The information provided in the flight data recorder can be of two types - parametric, containing data about the speed of the aircraft, its position in space, operation of engines and other. And speech containing radio conversations of the pilots. Recorded data is not encrypted, and a message in the news about the "deciphering black box", has approximately the same value as the "Transcript of talks."
