it will affect the flight. Once there is a thunderstorm area on a narrow route, it is sometimes possible to bypass the thunderstorm area. However, due to flight safety and national defense needs, civil aviation routes are strictly limited, and there is little room for flying around and turning around. When the thunderstorm area is large, this method will not work.

1. Delaying the flight

Although the height of the plane after taking off is higher than that of the thunderstorm clouds, it is very dangerous to take off through the thunderstorm layer when it thunders, and there is a risk of lightning strike. Moreover, the thunderstorm weather is generally fierce, and the wind speed and direction are unstable, so it is very difficult for the plane to take off. When it rains, the runway of the plane will be very wet, which will easily affect the taxi situation of the plane, so it is not suitable for taking off on thunderstorm days in all aspects.

2. Rainy takeoff conditions

It's not that the plane can't take off as long as it rains. In some rainy situations, the plane can still take off normally. First of all, it depends on whether the rain is heavy or not, and the visibility should be high, which will not affect the pilot's judgment, and there should not be too much water on the runway. In addition, it should be judged according to the situation of take-off and landing places. Different aircraft models have different degrees of influence. If the comprehensive conditions are suitable for take-off, the aircraft can take off normally even in rainy days.

Extended information:

The Civil Aviation Law stipulates: "The pilot-in-command has the right to refuse to fly if he finds that the civil aircraft, airport and meteorological conditions do not meet the requirements and cannot guarantee flight safety."

depending on advanced equipment, the meteorological department of civil aviation will continuously issue more accurate weather change trend forecasts to facilitate flight operation and scheduling. However, the weather conditions are constantly changing, and it is sometimes difficult to make a very accurate judgment. This will lead to the sudden deterioration of the weather conditions when the plane is about to land, which will make it impossible for the plane to land. For safety reasons, or it is difficult for the plane to continue hovering and wait for the weather to improve, the plane will have to alternate to other airports.

the constant change of weather may lead to bad weather for a short time. This will cause the plane to land in the weather five minutes ago and five minutes later, and some planes just caught up with the bad weather conditions for five minutes and could not land. At the same time, when the weather is on the edge of the standard, it is up to the captain to decide whether to land. The captain thinks that the weather is not suitable for landing, and has the right to decide to alternate to other airports or return for safety reasons.

In a word, the weather reason is not only the weather condition of the city where the destination airport is located. Aircraft take-off and landing are not afraid of strong winds and heavy rain, but the key factors are meteorological factors such as visibility, low clouds near the airport take-off and landing channel, thunderstorm areas and strong crosswinds. It is normal for flights to be delayed due to weather.
