3.2 1 What was the cause of the crash of China Eastern Airlines? Is it related to the weather?

Personal opinion: it may be the cause of aircraft failure, or it may be related to cold and warm air flow. The real reason can only wait for the black box to give the data answer. What's the latest news about the crash of China Eastern Airlines?

First, the black box of the tape recorder was sent to a beautiful country to repair and read audio information. Mainly to find the cause of the plane crash as soon as possible.

Second, the national accident investigation team composed of beautiful countries has arrived at the scene of the accident and launched a comprehensive investigation.

Thirdly, at the end of April, China Eastern Airlines gave a preliminary report on the plane accident, and preliminarily analyzed the cause and process of the accident.

Fourth, compensation for the victims is under way. The insurance company has paid1.1.60 million yuan to China Eastern Airlines and 1.4 million yuan to the families of the victims.

What is the main cause of the plane accident?

1, the fault of the aircraft itself. This phenomenon is caused by the failure of the aircraft itself, including the components of the aircraft, or the failure of the automatic operating system. Just like the brake pads of our car are broken, not because of technology, but because of the brake pads.

2, the cause of human operation. Man-made operation mainly refers to the pilot's operation technology, or the pilot's quality, including the pilot's technical operation mistakes, aircraft maintenance mistakes before flight and so on.

The fault is caused by the weather. Generally speaking, it refers to the aircraft out of balance caused by strong convective weather, or an unexpected phenomenon. For example, thick clouds, snowstorms, thunderstorms and other weather can cause plane accidents. Another situation may be cavitation, a natural disaster, which is hard to see. According to the video, when the accident happened, the sky was overcast.

According to the relevant information provided by China Eastern Airlines, the crash of China Eastern Airlines passenger plane:

(1) The aircraft can perform the flight mission after passing the inspection before taking off;

(2) The three pilots on the plane are experienced and have a harmonious family. The plane was pulled up for rescue within two minutes of falling, and the probability of human factors was low;

(3) In terms of weather reasons, the visibility over Wuzhou was very good at that time, and there was no strong convective weather;

(4) This plane was purchased on 20 15. By the time of the accident, it had been in operation for 6.8 years, and it was still a new plane.

Based on the above four reasons, the most likely reason is the cause of aircraft failure, and of course, the possibility of cavitation is not ruled out.

Is the cause of the crash of China Eastern Airlines related to the weather?

On March 2 1 day, Wuzhou Meteorological Observatory issued a weather forecast. Affected by strong cold air and shear line, from the night of March 2/kloc-0 to the 22nd, there was moderate rain in the whole city, heavy rain in some areas, accompanied by short-term thunderstorms and strong winds, and the temperature dropped as high as 10℃.

According to the temperature of the day, the highest surface temperature in Wuzhou is between 14: 00 and 4: 00 noon, and the highest temperature reaches 30℃, which can be said to be the feeling of entering summer. The weather forecast shows that there will be strong convective weather such as heavy rain in the evening, which shows the sultry situation before the heavy rain.

When the cold air drops and the outside air rises, it will form an air flow that moves up and down in the air, which is called "cavitation" in weather. In other words, the surface temperature has reached 30℃. Before the arrival of strong convective weather, the scene area of the plane accident was mountainous, the hot air pressure on the ground was relatively high, and the warm air rose sharply. A powerful air cavity may have been formed, and at this time, the passenger plane of China Eastern Airlines may pass by unfortunately, resulting in the fuselage and wings of the aircraft being impacted by cold and warm air currents and falling vertically under the action of gravity.

What happened to the crash of China Eastern Airlines passenger plane?

According to relevant videos and witnesses, the plane fell vertically to the ground within the visual range. Experts speculate that the plane landed at a speed of up to 200 meters per second and exploded when it hit the ground, igniting smoke and causing mountain fires.

China Eastern Airlines passenger plane hit the ground vertically, causing a crater with a radius of 30 meters and a depth of 20 meters. The plane exploded and burned after touching the ground.

According to the search and rescue results, the scene of the accident was terrible and a mess. The plane was torn to pieces and no relatively complete remains of the victims were found. It can be said that it is a very rare aviation accident.

In short, the main cause of the plane crash is still a mystery. We can only wait for the data recorded by the two black boxes on the plane to be read, and only through expert analysis can we give the real answer, and the reason can only be seen. May the deceased rest in peace and have a good trip!
