What is the real reason for the frequent delay of domestic flights?

The simple word "weather reason" actually contains many situations: the weather conditions at the departure airport are not suitable for take-off; The weather conditions at the destination airport are not suitable for landing; Meteorological conditions of flight routes are not suitable for overflight, etc.

2. Traffic control

In this case, the explanation of civil aviation is even less, because it is considered that it is not its own reason and it is impossible to change this situation. It can only wait for the notice honestly, and it is useless for passengers to worry.

3. Mechanical failure

Once an aircraft breaks down during the flight mission, the crew should make necessary inspection and judgment according to the maintenance procedures, analyze the fault phenomenon, find the source of the fault, and then carry out corresponding troubleshooting work, such as replacing the faulty parts. After troubleshooting, it is necessary to fill in the relevant maintenance records, and it is also possible to carry out certain testing work to determine whether to repair.

The whole troubleshooting process takes some time. Even some minor faults, there must be a set of strict maintenance and inspection procedures to ensure flight safety.

4. Passenger reasons

There are many reasons for flight delays, some of which are irresistible natural factors. It is worth noting that some human factors have become "new growth points" that cause flight delays. According to statistics, flight delays caused by passengers account for 3% of abnormal flights, which is almost the same as the number of delays caused by aircraft failures.

5. Aircraft deployment

In fact, this is not the reason for the delay. All other specific circumstances lead to the delay of subsequent flights, and civil aviation is counted as a plane delay. All the reasons for the delay of the plane are called plane deployment.

6. Flight cut in line

Airlines claim that they are victims of flight delays, and only 10% is controllable, and some of the delays are caused by "jumping in line" by planes.

Extended data:

Reward and punishment mechanism

The Civil Aviation Administration of China has established a reward and punishment mechanism to ensure the normal flight, that is, flight delay statistics and early warning. It publishes delay information once every 15 days, and conducts internal early warning notifications for 20 domestic flights with normal flight rates below 50%, and publishes early warning notifications twice a month.

Flights that are warned twice a month due to the airline's own reasons will be cancelled from next month after approval. For flight delays caused by air traffic control, airports, oil and other reasons, it is necessary to find out the reasons and impose penalties.

In addition, if the flight is delayed for more than 4 hours, and mass incidents are caused by airline aircraft deployment and self-service, which has a significant social impact, the airline will cancel the flight time of the current season and will no longer accept the application for the flight time of the next season.
