The flight data of China Eastern Airlines MU5735 showed that the crew tried to save the plane. Why did it fail?

This question can't be answered at present, because the complexity may be far beyond our imagination when the accident happened. Find the black box and interpret the data to know the final answer.

I think as long as a normal pilot, in the event of an accident, he will do his best to save the passengers, even at the expense of his own life. Judging from the flight data of China Eastern Airlines MU5735, the crew did try to save the plane. According to the data of MU5735 in FR24, the plane climbed to an altitude of 8907 meters at 13: 26, and then maintained at this altitude with a speed of about 845 km/h. ..

14: 20, 43-59 seconds, the altitude of the plane suddenly dropped from 8870 meters (29 100 feet) to 8237 meters (27025 feet), and the vertical speed reached-/kloc-0 at 14: 20: 59.

14:2 1:45 seconds, the plane descended to an altitude of 2393 meters (7850 feet). From then on, the vertical speed of the aircraft changed from negative to positive, reaching about 18 m/s (3250) at 14 min 2 1 min 55 sec.

After that, the speed of the plane continued to increase, rising to 37 m/s (7360 ft/min) and 43 m/s (8448 ft/min). 10 seconds later, that is, 14: 22: 05, the plane rose to 2622 meters (8600 feet) and climbed nearly 400 meters. This means that the pilot may still be awake at an altitude of more than 2000 meters, trying to save the lives of the plane and all passengers.

But then the vertical speed suddenly changed from positive to negative, 14: 22: 35, the altitude of the plane was 983 meters (3,225 feet), and then it crashed. That is to say, during the sudden and rapid descent of the plane, the crew should have tried to pull up the plane to restore it to the normal flying height, and it did have certain effect when it was more than 2,000 meters, but then the plane suddenly descended, and finally the crew failed to save the plane.

But I think for the crew, they have rich flying experience. If man-made control can save the plane, they will certainly do their best. But if there are some special circumstances in the plane that are beyond the control of the crew, there is nothing they can do. For example, MU5735 of China Eastern Airlines fell from a height of more than 8,000 meters in just over two minutes, and it fell vertically. This situation is hard to understand.

This shows that when the plane crashed, there may have been some failures that could not be manipulated or predicted by human beings. As for what the fault is, we have to find the black box to know the final answer.

Before that, I don't think we should read too much. After all, we are not professionals. Without accurate data, even professionals dare not draw conclusions easily.
