Can the plane take off normally in heavy rain?

The impact of heavy rain on flight lies in:

1, poor visibility

2. downward flow

3. Lightning (only in thunderstorm weather)

Whether it can take off and land depends mainly on whether the degree of harm exceeds the take-off and landing standards.

The standards of aircraft take-off and landing are divided into three categories: blind landing, blind landing and blind landing. Blind landing is the common name of ILS (Instrument Landing System). Because the instrument landing system can guide the aircraft to land in the low weather standard or the weather where the pilot can't see any visual reference, it is called blind landing. The highest standards for aircraft take-off and landing are three kinds of blind landings. In the case that nothing can be seen by the naked eye, the aircraft can take off and land completely by relying on instruments; The visibility is 400 meters or the runway visual range is not less than 350 meters, and the decision height of the minimum landing standard is not less than 30 meters, which is a second-class blind descent; The minimum standard is a blind descent, the meteorological standard is that the visibility in front is not less than 800 meters or the runway visual range is not less than 550 meters, and the decision height of the minimum landing standard is not less than 60 meters. The classification of the three types of ILP standards is uniformly stipulated by ICAO and is common all over the world. At present, China's Capital International Airport, Shanghai Pudong Airport, Chengdu Shuangliu International Airport and Guangzhou New Airport have Class II ILP standards, and other airports, including Changsha Huanghua Airport, have Class I ILP equipment support level.

What kind of blind landing aircraft can be realized is determined by the airport equipment support ability, aircraft technical status and the comprehensive technical level of aircraft pilots. Drivers are also divided into three grades accordingly. For example, although the Capital Airport has the second-class blind landing standard, if the technical condition of the aircraft is not up to standard, or the pilot does not have the second-class blind landing qualification, it will not take off and land.

You can't answer this question for sure. It depends on luck.
