Under what weather conditions can't the plane take off?

Among many weather phenomena, thunderstorms, low visibility, low clouds, low-altitude wind shear, typhoons, bumps, ice accumulation and volcanic ash clouds are the main threats to flight safety.

Thunderstorm is one of the worst and most dangerous weather encountered by aircraft in flight. Thunderstorm area has always been regarded as a "forbidden area" for flight activities. If the only way is blocked by Lei Yun, then the plane can't take off. Therefore, sometimes the take-off airport and landing airport are both clear-sky Wan Li, but the delay or cancellation of the plane may be due to bad weather such as thunderstorm on the flight route.

Low visibility weather has a great influence on the take-off and landing of aircraft. Rain, clouds, sandstorms, floating dust, smoke, fog and haze will reduce visibility and affect flight. The visibility on the ground is low, and it is easy to yaw and get lost, which affects the take-off and landing. When the visibility of the airport is less than 350 meters, the plane cannot take off; When it is less than 500 meters, the plane cannot land; If the visibility is less than 50 meters, the plane can't even taxi, and improper operation by the pilot can easily lead to flight accidents.

Low cloud is also one of the dangerous weather that endangers flight safety, which mainly affects the landing of aircraft. If the airport is covered with low clouds, the plane will be very close to the ground after flying out of the low clouds. If the plane is not aimed at the runway at this time, it is often too late to correct it, which is easy to cause a go-around. Sometimes, due to improper command or operation, the plane may collide with obstacles on the ground, causing accidents.

1. Fasten your seat belt and remember the safety door.

In order to reduce the impact on yourself when the plane crashes, the best way is to fasten your seat belt, follow the safety tips of the plane, keep bending over and hold your ankles with both hands. Of course, you have to learn how to unfasten your seat belt as quickly as possible. High heels and so on may not only hinder escape in an air crash, but also create additional dangers. Secondly, choose the emergency door, remember your position and the number of seats between the emergency doors to avoid getting lost when the cabin is full of smoke.

2, direct flight is preferred, don't hold the baby.

Since most air crashes occur in the take-off and landing phases, direct flights should be chosen as far as possible, which can minimize the number of take-off and landing. Although children sometimes have an advantage over adults in some aspects and have a greater chance of surviving in an air crash, they may be more dangerous to babies held in their parents' arms. In the event of an air crash, the baby may be thrown out under the impact, and parents often lean forward and hold the child when the plane crashes.
