Why did the flight suddenly cancel?

There are many reasons for flight cancellation, including bad weather, limited equipment conditions, national orders, public health, natural disasters and so on. Details are as follows:

1, weather

If the flight is due to the weather, it not only refers to the weather conditions such as rain and snow that can be seen when the plane takes off and arrives at the airport. The key meteorological factors affecting aircraft flight are low visibility, low clouds and thunderstorms near the airport take-off and landing passages, and strong crosswinds; So Wan Li is not suitable for flying just because it is clear.

2. Air traffic control

Flight air traffic control will also cancel the flight. Air traffic control means that many planes take off and land at the same time. In order not to affect the take-off and landing tasks of subsequent flights, it is necessary to control the planes that are about to land but still flying in the air and the flights that are about to take off.

3. Flow control

Flight flow control will delay or even cancel flights. Flight flow control refers to maintaining air safety by limiting the number of aircraft entering an air traffic control node per unit time.

4. Aircraft mechanical failure

When there is something wrong with the plane, the flight will be cancelled due to mechanical failure, which is often encountered. Safety is the most important thing.

5. Others

Due to the turnover of airlines' aircraft, the aircraft has a major failure, which cannot be repaired in a short time, and the aircraft turnover cannot come; From the perspective of tourists, the number of round-trip passengers on this flight is small, and it may be cancelled in order to reduce operating costs.
