Can the plane take off normally in moderate rain?

You can usually take it off. Under normal circumstances, rain will not affect the take-off of aircraft, unless it encounters strong convective weather and unpredictable wind shear, which will affect the flight trajectory and attitude and affect flight safety. It depends on the type of rain. If the rainfall intensity is small and the engine performance and visual conditions are not affected, the plane can take off. However, if the runway visual range does not reach the minimum value due to precipitation, and the accumulated water in the runway area exceeds 3mm, there will be some important weather phenomena that directly affect the airport environment, such as strong and low-level wind shear, thunderstorm, downburst or cumulonimbus clouds, and the plane cannot take off. Extended information: the situation that the plane can't take off in rainy days: First of all, if the rainfall intensity is small, it will not affect the engine performance and visual conditions. 2. If the reason for precipitation is: 1. Runway visual range cannot reach the minimum value. 2. The runway area is greater than 3mm. 3. There is strong low-level wind shear. 4. Important weather phenomena such as thunderstorms, downbursts or cumulonimbus clouds will directly affect the airport environment.
