The Influence of Thunderstorm on Aviation in thunderstorm cell

Thunderstorm clouds carry a lot of charge. When an airplane flies in a thunderstorm area, the induced charged charge is very large, and sparks jump at the tips of the two wings of the airplane, which affects the antenna communication. Therefore, it is stipulated that aircraft must not cross the thunderstorm area and must fly around it. It is stipulated that the bypass outside the cloud should not be less than 5km during the day and10km at night. Generally, thunderstorm weather is reflected in three colors on radar: red area, yellow area and green area. The red area and the yellow area can't enter, so we should go around, and the green area can pass, so we should be vigilant.

Aircraft will encounter turbulence in flight, and the turbulence in cumulonimbus clouds is strong, so the turbulence when the aircraft passes through cumulonimbus clouds is also extremely strong. The greater the turbulence of the aircraft, the greater the change of the load borne by the fuselage. When the load borne by the fuselage exceeds the maximum value, some parts of the aircraft will be deformed or even damaged. Strong turbulence makes the plane swing violently, which is difficult to control, and may make the plane rise or fall several meters or even hundreds of meters at the flying height instantly.

When thunderstorms occur, they are often accompanied by gusts with fast wind speed and large wind direction changes. Although it doesn't last long, it seriously threatens the safety of the aircraft during the take-off and landing phase, and may also damage the ground facilities of the airport. Heavy rain accompanied by thunderstorm makes the visibility worse, and the pilot can't see the runway clearly when landing, which is easy to cause a go-around.
