Can planes fly when a typhoon comes?

Normally, planes cannot take off when a typhoon comes.

Because the typhoon is an anticyclonic outflow airflow at the upper level, and the low-pressure flow direction is mainly the intervening airflow at the lower level. In this case, if the aircraft flies, it will experience severe turbulence, and the aircraft fuselage will be in an uncontrollable position. status, flight safety will be greatly affected. In addition, typhoons are usually accompanied by heavy rain or heavy rain. When an aircraft passes through a minefield, the electric field on the aircraft's fuselage, wings and other protruding parts is very strong, making the aircraft prone to lightning strikes.

If conditions permit take-off, the crew will determine the location and trajectory of the typhoon based on the weather cloud map, and prepare a reasonable route around the typhoon before flying. At the same time, during the flight, pilots must fully understand the weather conditions around the route and destination airport, avoid severe weather such as thunderstorms, and communicate well with the control department. If the captain feels that the conditions at the destination airport are not suitable for landing, he should make a decisive go-around or choose an alternate landing.

The impact of typhoon on flight:

1. Turbulence. Typhoons are mainly low-pressure inflow airflow at low levels, which can produce strong wind speeds in the inner area, and anticyclonic outflow airflow at upper levels. The upper and lower circulations are connected through strong upward motion, which is the main feature of typhoon circulation. Rising and falling airflow will cause violent turbulence in the aircraft, seriously affecting flight safety.

2. Freezing. Thunderstorm clouds in the mature stage contain a large number of supercooled water droplets. When the aircraft passes through the clouds, the small water droplets encounter the surface of the aircraft and easily freeze. Pilots must pay close attention to this situation, observe and use the de-icing and anti-icing systems in a timely manner.

3. Hail. Typhoons sometimes produce hail. The plane was flying too fast. Aircraft surfaces are easily struck by hail.
