What are the natural reasons that will cause the plane to stop flying?

1) Bad weather:

There are countless air crashes closely related to the weather, such as the recent Yichun air crash, 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. 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, there are many examples of plane crashes that are caused by cold weather and wind shear during take-off and landing, which is also commonly known as "strange wind".

2) 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. 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. 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 navigation of aircraft.
