1982 causes of American air crash

There are two reasons for this air crash: one is extreme weather; First, there are mistakes in management and operation.

First, look at extreme weather. 1982 65438+1October 13, the worst snowstorm in the history of Washington, D.C. hit the city. At that time, almost everything-government, enterprises, schools and airports-stopped. When preparing for the flight, it was sunny in Wan Li, but the wings of our plane were covered with thick ice and snow, and the speed detection system was also covered with ice and snow. Pilots are obviously not used to the snow and ice weather in Washington, and flying in such extreme weather is full of danger.

Second, look at the mistakes in management and operation. The crew found ice and snow on the wing, but they simply deiced it at the scene instead of returning to the tarmac. The rotational speed detection system on the engine nose is covered with ice and snow, which provides wrong rotational speed readings, making the pilot mistakenly think that the thrust meets the takeoff requirements. When taking off, the ice and snow on the wing weakened the lift of the plane, and the plane finally got out of control after barely taking off. The pilot and co-pilot once realized that the acceleration was too slow, but the captain said there was no problem, which eventually led to great disaster.
