How far is it before the plane takes off from the typhoon?

Typhoon is a large cyclone storm, usually formed in tropical or subtropical areas, which will have a great impact on the take-off and landing of aircraft.

Planes usually fly at an altitude of 6000- 19000 feet (1830-579 1 m), while typhoons usually reach an altitude of more than 10 km. So the plane needs a certain distance from the typhoon to take off safely. Specifically, if the typhoon center is located near the airport, it is usually necessary to wait for the typhoon to pass before taking off. If the typhoon center is far away from the airport, it is also necessary to ensure that the plane is at least 600 kilometers away from the typhoon center.

In addition, if the plane encounters a typhoon during the flight, the pilot needs to take appropriate measures, such as changing the route or lowering the altitude, to avoid encountering a typhoon head-on.

In short, in order to ensure the safety of the aircraft, it is necessary to carefully evaluate the situation of the typhoon and take corresponding measures to ensure that the distance between the aircraft and the typhoon is safe enough.
