It snowed the day before, can the plane fly the next day?

It snowed the day before, and whether the plane can take off the next day depends on the actual weather.

If it is a light snow day without snow, the impact is not great, and the plane can fly. 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.

Whether there is snow on the runway and whether the plane is completely deiced is a key to judge whether the plane can take off and land normally. If there is heavy snow, which hinders people's sight and affects visibility, it will generally not take off normally. At the same time, the runway was covered with snow and fluctuated in the snow. Landing will change the resistance, tire skidding, which is not conducive to flight, and will also cause flight delays and slow flights in and out of Hong Kong.

Influence of visibility on aircraft

During the take-off and landing phase of the aircraft, the low visibility caused by rain and snow will make the pilot unable to see the surrounding things, buildings and runways, which will cause the aircraft to drift or get lost and affect the normal and safe landing of the aircraft when landing. If the pilot does not handle it properly, it will lead to an accident.

Low visibility is equivalent to covering the pilot's eyes. If the visibility on the route is low, it will affect the navigation of landmarks. If the visibility of the target area is very low, it will have a serious impact on activities such as visual landmark flight, airdrop, photography and inspection. Therefore, it is very dangerous for aircraft to encounter low visibility environment during take-off and landing or flight.
