Will sleet turn to light snow affect the take-off of the plane?

If it doesn't snow, there is not much rain and snow, and the visibility can reach the airport standard, you can take off. However, if there is snow or ice on the runway, the friction coefficient of the runway is less than the coefficient required by law for aircraft take-off and landing. For safety reasons, flights will be delayed, changed or cancelled.

The weather that has the greatest impact on aviation safety in winter is snow (including ice particles, rice snow and sleet) and freezing rain. Rain and snow will cause the surface of the plane to freeze. It takes no more than half an hour for the plane to fly from the ground to an altitude of 8 thousand meters or even 10 thousand meters, and some even take more than ten minutes. In rainy and snowy weather, the air contains a lot of condensed water.

When the plane takes off from the airport, the condensed water will adhere to the surface of the plane. When the plane is afraid of rising to the sky, because the air temperature in the sky is much lower than 0℃, the water attached to the surface of the plane becomes ice, which will absorb the moisture in the atmosphere and freeze again, and the ice layer will become thicker and thicker.

Extended data:

Factors affecting the take-off or landing of aircraft;

1. Weather conditions at the departure airport (visibility, low-level clouds, thunderstorm area, strong crosswind).

2. Weather conditions at the destination airport (visibility, low-level clouds, thunderstorm area, strong crosswind).

3. Meteorological conditions on the flight route (high-altitude thunderstorm area).

4. Condition of the unit (technical level of the unit, analysis and grasp the current weather and trends to make professional decisions).

5. Aircraft condition (under the premise that the aircraft meets the safety standards of meteorological conditions, due to the failure of some airborne equipment, the aircraft is not suitable for flying in this weather condition).

6. The follow-up situation caused by bad weather (mostly the airport navigation facilities are damaged, the runway is not up to standard, such as icing, serious water accumulation, etc. ).
