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

Although the probability of a plane crash is very small, looking at the history of plane crashes, it is still terrible. So, do you know the cause of the plane crash? There is a lot of bad weather, which is closely related to the weather. For example, the Ichun air crash, the Pakistan air crash and the Polish presidential plane crash were all accompanied by thick fog. Air crashes caused by lightning sometimes occur in the summer. The cause of the Colombian air crash was that the plane was struck by lightning and then broke into three pieces when landing, killing one person and seriously injuring five others. According to statistics, there are two air crashes caused by lightning every year. However, since 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 and generally will not have a serious impact on the aircraft. In addition, during the take-off and landing of aircraft, there are many aircraft crashes caused by cold weather and wind shear, commonly known as strange winds.

Electromagnetic interference, why is it so dangerous to use mobile phones on airplanes? It turns out that the navigation equipment on the aircraft uses electromagnetic waves to determine direction. After receiving the electromagnetic waves continuously emitted by the ground navigation station, it can measure the accurate position of the aircraft. When the mobile phone is working, it will also radiate electromagnetic waves, which will interfere with the aircraft's navigation equipment and control system, causing the aircraft's automatic control equipment to receive wrong information, thereby performing wrong operations, causing danger, and even causing the aircraft to crash. In addition to mobile phones, laptops and game consoles also radiate electromagnetic waves, so these devices cannot be used on airplanes. In addition, electromagnetic waves generated by astronomical phenomena such as sunspots and northern lights can also interfere with the normal flight of aircraft.

There are some human reasons, such as pilot error. After all, pilots are human beings. Even if they have received professional training, there is no guarantee that they will never make mistakes. For example, in the crash of Japan Airlines Flight 350, the mentally ill captain deliberately turned on the thrust reverser of the plane's engine in an attempt to crash the plane, which eventually caused the plane to fall into the water, killing 24 passengers. The ground crew made a mistake during maintenance. Including improper loading and unloading by ground staff, illegal maintenance, etc., it is equivalent to placing a time bomb on the aircraft, and accidents may occur at any time. For example, during takeoff, American Airlines Flight 191 fell due to rough engine loading and unloading, which eventually led to the plane crash; during the flight, Alaska Airlines Flight 261 lost control because the tail servo was not replaced regularly, causing the plane to crash. Plunging into the icy Atlantic Ocean. It is indeed due to the slackness and irresponsibility of the ground staff that a disaster that should not have happened became a reality.

Pilot/ground crew communication error, Tenerife air crash, deadliest in aviation history, 583 people lost their lives due to language barrier between pilots and ground crew. Due to heavy fog at the airport that day, the two Boeing 747s waiting to take off on the slide could not meet each other. Because the pilot of one of the planes was not speaking to the air traffic controller, they misheard the order to start the plane, causing both planes to take off at the same time and a tragic collision occurred on the slide. The cause of the Indonesian air crash was that the air traffic control center caused the plane to go in the wrong direction, causing the plane to hit a mountain and be destroyed. In addition, because air traffic control personnel did not clearly report altitudes to pilots, expressed vaguely, violated procedures, etc., air accidents occurred one after another.
