Part of the wreckage of the crashed passenger plane in Indonesia and a large number of passengers' belongings were salvaged ashore. What are the common causes of plane crashes?

Although the probability of plane crash is very small, it will be terrible to look at the history of plane crash. So, do you know the cause of the plane crash? There are many bad weather, which is closely related to the weather. For example, the Yichun air crash, the Pakistan air crash and the Polish presidential plane crash were all accompanied by dense fog. Air crashes caused by lightning sometimes occur in summer. The cause of the air crash in Colombia was that the plane was struck by lightning and then broke into three parts when landing, resulting in 1 death and 5 serious injuries. According to statistics, there are two air crashes caused by lightning every year. However, because the aluminum alloy used as the aircraft shell is a good conductor, when the aircraft is struck by lightning, the current will spread through the aluminum alloy shell, which generally will not have a serious impact on the aircraft. In addition, in the process of taking off and landing, many plane crashes are caused by cold weather and wind shear, commonly known as strange wind.

Electromagnetic interference, why is it dangerous to use a mobile phone on an airplane? It turns out that the navigation equipment on the plane uses electromagnetic waves to determine the direction. It can measure the exact position of the plane after receiving the electromagnetic waves continuously emitted by the ground navigation station. When the mobile phone is working, it will radiate electromagnetic waves, interfere with the navigation equipment and control system of the aircraft, and make the automatic control equipment of the aircraft receive the wrong information, thus making the wrong operation, causing danger and even crashing the aircraft. In addition to mobile phones, laptops and game consoles also radiate electromagnetic waves, so these devices can't be used on airplanes. In addition, electromagnetic waves generated by astronomical phenomena such as sunspots and northern lights will also interfere with the normal flight of aircraft.

There are some man-made reasons, such as pilot's operation error. After all, pilots are human. Even if they have received professional training, there is no guarantee that they will never make mistakes. For example, in the air crash of Flight 350, the mentally ill captain deliberately turned on the anti-thrust device of the aircraft engine in an attempt to crash the aircraft, which eventually caused the aircraft to fall into the water, killing 24 passengers. The ground crew made a mistake in maintenance. Including improper handling and illegal maintenance by the ground crew, it is equivalent to putting a time bomb on the plane, and accidents may occur at any time. For example, during the take-off of American Airlines 19 1 flight, the plane crashed due to rough engine handling, which eventually led to the plane crash; Alaska Airlines Flight 26 1 lost control during the flight because the tail steering gear was not replaced regularly, and the plane crashed into the icy Atlantic Ocean. This is indeed due to the slackness and irresponsibility of the ground crew, which made the disaster that should not have happened become a reality.

Communication error between pilots and ground crew, Tenerife air crash, the largest number of deaths in aviation history, 583 people were killed because of the language barrier between pilots and ground crew. Due to the fog at the airport that day, two Boeing 747s waiting to take off on the slide could not meet. Because the pilot and air traffic controller of one of the planes didn't understand the language, they mistakenly listened to the command to start the plane, which led to the two planes taking off at the same time and a tragic collision on the slide. The cause of the air crash in Indonesia was that the air traffic control center caused the plane to go in the wrong direction, which led to the plane crashing into a mountain and being destroyed. In addition, the air traffic controllers did not clearly report the altitude to the pilots, and the expression was vague and violated the procedures, resulting in an endless stream of air crashes.
