Black box data is still being repaired. How difficult is it to repair the black box data?

Recently, the problem of repairing the black box has aroused people's heated discussion, especially the black box has been found and sent to the United States, which can be said to have touched the hearts of the people all over the country. But many people are curious, why does it take so long to find the contents of the black box, and why does it have to be sent to the United States to decrypt the related black box? How difficult it is to repair the data of the black box with so much time and process has caused discussion among netizens.

First, the black box is a damaged black box, so it is difficult to guarantee that the contents will not be damaged. You know, the accident of China Eastern Airlines happened at an altitude of several thousand meters. If an object falls from a height of several thousand meters, it will basically suffer great damage. Of course, the black box is made of special materials, which can ensure that the black box will not be damaged as much as possible, but in any case, falling from such a high place will definitely hurt, so the first step is to say. This step is difficult, so it needs more time.

Second, the decryption of the black box needs to cooperate with airlines. The airline of China Eastern Airlines in the United States is the famous Boeing Company. Many of our planes are produced by Boeing, so as a foreign company, the setting of black boxes is different from that of our domestic company. In order to ensure the rigor of black box data, basically all companies will set that only companies that produce black boxes have the ability to decrypt black boxes. In order to ensure this, they will strictly encrypt black boxes.

Third, the amount of data in the black box is very large, which is very difficult to repair and takes a long time. First of all, the black box not only recorded the parameters of the plane at that time, but also recorded a lot of different data, such as the crew's conversation in the air, whether the various switches of the plane were turned on, when they were turned on, what the crew did, and so on. These data are very critical, and the environment on the plane can be completely simulated by these data.

I hope the black box can be repaired as soon as possible and the truth of the incident can be restored as soon as possible.
