Can the plane take off normally under heavy snow?

Not necessarily. There is a weather forecast at the airport every day. According to the weather forecast, there will be tips for taking off and landing flights at the airport. If the weather is bad enough, the airport will be temporarily closed. Even if the weather at this airport is good and the weather where you fly is bad, the flight will be cancelled.

If there is no snow on the runway and no ice on the wing, the visibility can be allowed to fly, such as whether there is snow on the runway, whether the plane is completely deiced, and snowy days hinder people's sight, which is generally not conducive to flying. The runway is covered with snow. When taking off and landing on the snow, the resistance will change, the tires will slip, which is not conducive to flight, and it will also delay flights and slow down the speed of entering and leaving the port. It doesn't matter much in light snow, so the plane can fly.

Extended data:

Meteorological problems that have great influence on the air are: clouds, fog, precipitation, smoke, haze, sandstorm and floating dust, which will reduce visibility. When the horizontal and oblique visibility of the airport drops below the critical value, resulting in line-of-sight obstacles, it will be difficult for the aircraft to take off and land. When the horizontal visibility is less than1500m, the runway sight distance should be observed at the airport with instrument landing facilities. Although the aircraft can land in low visibility in airports with instrument landing system, it is difficult for the aircraft to land in larger airports in the world when the runway sight distance is less than 400 meters and the judgment height is less than 30 meters.
