What level of wind can't fly?

A strong storm above magnitude 9 can't fly.

Basically, the wind speed in life is 0~8, so you can fly.

Among them, the wind speed below level 5 has no effect on the take-off of the aircraft.

Strong winds of 6-8 are rare (8 winds will break branches and make it difficult to walk head-on), but even if you encounter 6-8 winds, you need to look at the wind direction.

Extended data:

Five winds that affect the flight of aircraft;

The wind blowing towards the plane. Most planes take off or land against the wind because the wind will increase the lift.

Downwind, the wind blowing from the back of the plane. Downwind will reduce lift, and airplanes usually avoid taking off or landing with downwind.

A crosswind, a wind blowing from the side. If the plane encounters a sudden change in crosswind when landing, it may deviate from the center line of the runway.

Wind shear refers to the change of buoyancy caused by the change of headwind or tailwind that lasts for more than a few seconds. The decrease of buoyancy will cause the plane to deviate downward and fall below the predetermined flight path.

Turbulence is caused by the rapid and irregular flow of the atmosphere. It makes the plane bumpy, and in severe cases, the plane may temporarily lose control.
