How long is the plane usually late?

The weather won't last long, usually 3 hours! The aircraft is delayed due to military activities, and the delay time shall be determined according to the end time of military activities.

The possible reasons for the aircraft delay are as follows:

First, the weather;

1, weather is the main reason for flight delay, and it is generally believed that bad weather is obvious, which leads to flight delay.

Passengers on the wrong bus can understand, but they are not.

2. At present, the explanation of civil aviation for the delay caused by bad weather is that the weather can't meet the flight standard and can't be on time.

Take off.

3. From the passenger's point of view: Bad weather means strong wind, heavy rain and fog, planes may not be able to take off and land, and flights may be delayed. but

This kind of understanding is one-sided, and it will also cause many misunderstandings. Think that civil aviation is cheating, especially some flights can go.

Some can't leave.

4. Weather criteria for flight, take-off and landing are: weather conditions at the take-off airport (visibility, low-level clouds, thunderstorm areas,

Strong crosswind); Weather conditions at the destination airport (visibility, low-level clouds, thunderstorm area, strong crosswind); Cell state (cell technology)

On the technical level, analyze and grasp the current weather and trends to make professional decisions); Aircraft condition (aircraft safety under meteorological conditions)

On the premise of full standard safety, some airborne equipment fails, which makes the aircraft unsuitable for flying in this weather condition); Because it is not good

Subsequent situations caused by the weather (mostly damage to airport navigation facilities, substandard runway, such as icing and serious water accumulation). ).

Second, air traffic control;

1, the impact of air traffic control on a flight is mainly due to two reasons.

2. Flow control: In recent years, China's civil aviation has developed rapidly, the number of flights has increased sharply, and the corresponding ground facilities and navigation facilities have been set up.

The development of equipment and service guarantee is slow, and the route structure is unreasonable, which can not adapt to the rapid development of the current civil aviation industry. Recent situation

The situation has improved, and radar control has been realized in some routes, effectively alleviating the phenomenon of tin pushing, but the overall progress is not great.

3. Air Force activities: This situation involves national defense secrets, and the control time is as short as half an hour and as long as three or four hours.

There are often a lot of traffic jams in the system and airspace, which can disrupt almost all related airports on the same day if it is delayed continuously and controlled once.

Flight operation makes civil aviation at a loss.

Third, mechanical failure;

1, once the aircraft breaks down during the flight, the crew should make necessary inspections according to the maintenance regulations and supplement them.

Judge, analyze the fault phenomenon, find the source of the fault, and then carry out the corresponding troubleshooting work, such as replacement.

Faulty parts, etc. After troubleshooting, you need to fill in the relevant maintenance records, and you may also need to do some testing work to

Determine if it has been fixed.

2. The whole troubleshooting process takes some time. There should be a set of strict maintenance checks even for minor faults.

Test procedures are needed to ensure flight safety.

Generally speaking, if the plane is in the base of the airline, the time to deal with the fault will be very short, even if it is a major fault.

It is difficult to repair, because it is easier to deploy in the base and the delay time will be shorter.

4. If the aircraft fault is outside the station, the local area may lack necessary maintenance equipment, parts and maintenance personnel.

It's really hard to say how long it takes to delay, which is related to the specific situation of the fault and the local maintenance ability. If it's a major mistake,

It is difficult to rule out at present, even if another plane is sent, it will take a long time.

Fourth, aircraft deployment;

1, this is actually not the reason for the delay. All other specific circumstances lead to the delay of subsequent flights and the unification of civil aviation.

Because the plane is late, all the reasons for the delay are called aircraft deployment.

2. Generally speaking, an airplane has to perform 6 to 10 domestic flights a day, flying in the sky for about 10 hours, plus

The average plane runs about 16 hours a day, such as getting on and off passengers, cleaning, loading and unloading cargo, routine inspection, etc. each

The flight plans of all planes are arranged in advance, and there is not much room for manoeuvre. Any omission in the previous flight may lead to

The chain reaction of continuous flight often leads to longer delays.

3. In reality, the airlines in China are very small, even though the three major aviation groups are divided into subsidiaries in operation.

Independent operation, low efficiency, small deployment space, imperfect supporting facilities such as routes and airports, resulting in flights.

The overall operation efficiency is low, and once an accident occurs, the response and deployment ability is poor. At present, airlines are also taking active actions.

Adjust and strengthen deployment capacity, strive to improve flight operation efficiency and reduce flight delays.

Verb (abbreviation for verb) military activities

1. Generally, there are fewer flights delayed for this reason.

2. Military activities are highly private, and flight arrangements are based on the principle of military priority.
