Under what circumstances can a plane not take off?

1. Weather reasons

1. The flight standards were not good enough and could not take off on time. The simple four words "weather reasons" actually include many situations: the weather conditions at the departure airport are not suitable for taking off; the weather conditions at the destination airport are not suitable for landing; the weather conditions on the flight route are not suitable for flying over, etc.

2. Weather conditions at the departure airport (visibility, low-altitude clouds, thunderstorm areas, strong crosswinds), destination airport weather conditions (visibility, low-altitude clouds, thunderstorm areas, strong crosswinds), on the flight route Meteorological conditions (high-altitude thunderstorm area):

2. Crew status

Crew status (crew technical level, analysis and grasp of current weather and trends to make professional decisions), aircraft status (the The aircraft model meets the safety standards for meteorological conditions, and certain airborne equipment fails to comply with the safety premise, causing the aircraft to be unsuitable for flying in such weather conditions)

3. Traffic control

Encountering this In this situation, the civil aviation industry has even fewer explanations, because it believes that it is not its own fault and cannot change the situation. It can only listen to the notification honestly, and there is no point in rushing. Civil aviation aircraft in the air are subject to many factors just like cars on the ground. In short, civil aviation aircraft take off, land and fly under limited space, limited time and limited conditions.

4. Follow-up conditions

Subsequent conditions caused by bad weather mostly refer to damage to airport navigation facilities, substandard runways, such as ice, severe water accumulation, etc. As a result, it was impossible to take off normally.

5. Mechanical failure

The aircraft is not allowed to take off if there is a malfunction. Sometimes the aircraft is notified after takeoff that the aircraft has malfunction and has to return or land nearby. Fault repair: most faults Hidden dangers will be dealt with in a timely manner during these routine inspections, and any problems that pose a threat to flight safety will be resolved before continuing the flight before taking off.

Extended information

Flight attitude

1. Aircraft flying in the air are different from vehicles moving on the ground. They have various flying attitudes.

2. The flight attitude determines the movement of the aircraft, affecting both the flight altitude and the flight direction. When flying at low speed, the pilot can judge the attitude of the aircraft by observing the ground and the position of the horizon.

Route

The route an aircraft flies is called an air traffic line, or route for short. The aircraft route not only determines the specific direction, start and end points and stopping points of the aircraft's flight, but also stipulates the width and flight height of the route according to the needs of air traffic control to maintain air traffic order and ensure flight safety.
