Has the content of China Eastern Airlines Black Box been announced?
It is understood that "black box" is one of the special electronic recording equipment for aircraft, and its real name is aviation flight recorder. It is equipped with flight data recorder and cabin sound recorder. There are usually two black boxes on each plane. Their scientific names are "flight data recorder" and "cabin voice recorder"
The former mainly records various flight data of the aircraft, including flight attitude, flight trajectory (track), flight speed, acceleration, latitude and longitude, heading and various external forces acting on the aircraft, such as resistance, lift and thrust. * * * About 200 kinds of data can save flight parameters for more than 20 hours. After this period of time, the data recorder will automatically spit out the old and absorb the new, and the old data will be overwritten by the new data. The cabin voice recorder mainly records the conversations between the crew and the ground personnel, the conversations between the crew and all kinds of sounds in the cockpit (including the running sound of the aircraft engine).
As can be seen from the above, the black box can record passengers' voices and flight data. However, not all the contents will be made public. First of all, the data information recovered by flight data recorder and FDR can be found in Boeing's database, but the content is professional and may be released in a small range of professional fields, but it will not be released like the press conference. Secondly, the recorded data of cockpit voice recorder and CVR are confidential and should not be made public; Finally, some recordings will be released.
The above is the introduction of the content of China Eastern Airlines Black Box. I hope it will help everyone.
