Why is it so difficult to investigate the air crash?

The reason why it is so difficult to investigate the air crash accident is the complexity of the structure of the aircraft itself and the complexity of the aircraft and the flight environment.

Aircraft is a highly complex mechanical system, which consists of thousands of components and systems. The interaction between these components and the system is very complicated, and any minor fault may lead to serious consequences. Therefore, investigators need to spend a lot of time and energy to understand the structure and function of the aircraft in order to determine whether there are any faults or failures.

The flight environment of aircraft is extremely complex, including high altitude, supersonic speed and strong wind. , as well as complex meteorological conditions, will have an impact on the operation and safety of aircraft. At the same time, the performance of the aircraft is also affected by many factors, such as the pilot's skills, the cooperation of the crew, the airport facilities and so on. Therefore, investigators need to consider many factors in order to understand the cause of the accident.

The cause of the air crash

There are countless air crashes closely related to the weather, such as the Pakistan air crash and the Polish presidential crash, all of which are accompanied by dense fog. However, air crashes caused by lightning strikes in summer often occur. On August 20 10, the air crash in Colombia was due to the fact that the plane was broken into three parts by lightning while landing, resulting in the death of 1 person and the serious injury of 5 people. According to statistics, there are two air crashes caused by lightning every year on average in the world.

The navigation equipment on the plane uses electromagnetic waves to determine the direction. After receiving the electromagnetic waves continuously emitted by the ground navigation station, it can measure the exact position of the plane. When the mobile phone is working, it will radiate electromagnetic waves, which will interfere with the navigation equipment and control system on the plane, so that the automatic control equipment of the plane will receive the wrong information, thus making the wrong operation, causing danger and even crashing the plane.
