Why are there no flights in China after 12 in the afternoon?

First of all, the safety of aircraft is mainly related to the weather, and the weather at night is more difficult to predict, because the temperature changes very quickly at night, so the risk factor of aircraft flying at night is relatively large. In addition, visibility is very low at night, so for pilots, the line of sight is blurred. Therefore, when flying at night, people's physical function will be reduced and their mental state will be worse than during the day. Therefore, when flying at night, pilots with rich flying experience can do this job well. However, even if experienced pilots fly at night, their flying ability will actually decline.

The third point is that when working at night, people's attention is difficult to concentrate, so accidents are prone to occur in flight. If there is an accident, rescuers will not arrive at the scene soon, so it is very difficult to rescue at night. Therefore, many passengers will lose the best escape time at night, which will greatly increase the possibility of accidents and loss of life.

The fourth point is because the speed of the plane is very fast, so for most people, people who know these things will not choose to fly at night, so even if airlines plan to fly at night, few people will choose to fly at night, so for airlines that fly at night, there will be no profit or even great loss. So they won't arrange a flight at night.

Policy. So there are not only no flights at night, but also no trains and buses at night. These all take into account the danger of traveling at night. Therefore, for everyone's safety, the country also prohibits the arrangement of flights after 12. I believe everyone can understand that the relevant regulations of the state have considered various factors and obtained the most suitable policy under the current situation.
