Can the thunderstorm plane take off normally?

The thunderstorm plane can't take off normally. From the point of view of flight safety, it can fly when it rains at ordinary times and does not affect normal visibility, except for thunderstorm weather. Aircraft flying in thunderstorm weather will have strong bumps, which will easily damage the aircraft structure, and strong lightning will also damage the aircraft.

Thunderstorms will threaten the safe operation of aircraft, mainly in:

1, heavy precipitation

When an airplane flies under, near or in a thunderstorm cloud, it may enter a heavy precipitation area. Heavy precipitation will cause the engine to inhale too much water and affect the engine. In the low-altitude landing stage, heavy precipitation will reduce the aircraft performance and affect the pilot's observation and judgment. In addition, the runway surface is slippery due to precipitation, and there have been accidents such as pilots' unclear vision, planes rushing off the runway and even plane crashes.

2. Lightning

Thunderstorm clouds contain huge energy, and they will show their terrible side in the form of electric discharge. Green, yellow, red and other colors often appear on radar pictures, and the intensity of precipitation (liquid) is expressed by radar reflection. In most cases, the intensity of reflected echo also represents the possibility of discharge at this position. If the plane is struck by lightning, it may cause damage to the body, failure of some navigation equipment or damage to system equipment.

3. Hail

Hail usually appears in or downwind of thunderstorm clouds. Hail is very harmful to fast-flying aircraft, which can lead to windshield rupture or radome damage in severe cases. If the engine or operating system is damaged by hail, the consequences are unimaginable.

4. Strong wind (wind shear)

Thunderstorm clouds are often accompanied by strong winds, and the wind direction and wind speed may change dramatically, resulting in strong turbulence of the aircraft. For example, in the low-altitude landing stage, there are not a few flight accidents caused by the sharp reduction of aircraft lift caused by the downburst and wind shear under the thunderstorm cloud.

5. Ice accumulation

Thunderstorm clouds are generally "tall", and supercooled water droplets often exist at some heights in the clouds. The cloud anvil blown by the wind at the top of the cloud is relatively large, and the air temperature is very low. Once the aircraft flies in these areas, it may encounter strong ice accumulation in a short time, which will lead to the attenuation of the flight performance of the aircraft.
