If it snows lightly at the airport, can the plane land?

According to civil aviation regulations, it is necessary to close the runway when there is snow, ice and water on the runway, and the standard for closing is not universal.

For different types of aircraft, the standards of runway water and snow depth are different, and the value of large aircraft is generally larger. If there is ice, then there must be no plane to use the runway. The reason why airplanes can't use the runway is that snow, water and ice have seriously affected the friction coefficient between airplane tires and the runway surface.

The light snow situation you are concerned about, the airport will not be closed, and the plane landing will not be affected. Because light snow melts easily, but if the temperature is very low and the melted snow meets ice, then you can't use the runway.

But generally, there are vehicles for deicing and snow removal in larger airports, that is, a jet engine is installed at the back of the truck, which relies on strong heat to remove snow and ice.
