Under what circumstances can't the plane land?

1, not up to the flight standard, can't take off on time. 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; The meteorological conditions of flight routes are not suitable for flying over and so on.

2. Weather conditions at the airport of origin (visibility, low-level clouds, thunderstorm area and strong crosswind), at the airport of destination (visibility, low-level clouds, thunderstorm area and strong crosswind) and on the flight route (high-level thunderstorm area):

Second, the unit status

Unit status (the technical level of the unit, analyzing and mastering the current weather and trends to make professional decisions), and aircraft status (on the premise that the aircraft meets the safety standards for meteorological conditions, due to the failure of some airborne equipment, the aircraft is not suitable for flying in this weather condition).

Third, traffic control.

In this case, the explanation of civil aviation is even less, because it is considered that this situation cannot be changed because of its own reasons. It's no use waiting for the notice honestly. Civil aircraft in the air, like cars on the ground, are restricted and influenced by many factors. In short, civil aircraft take off, land and fly in limited space, limited time and limited conditions.

Four. Subsequent state

The follow-up situation caused by bad weather refers to the damage of airport navigation facilities, icing and other unqualified runways, and serious water accumulation. It was caused by the failure to take off normally.

Five, mechanical failure

When the plane breaks down, it is not allowed to take off. Sometimes I am told that the plane should return or land nearby after taking off. Troubleshooting: Most hidden dangers will be dealt with in time during these routine inspections, and all problems that pose a threat to flight safety will be solved after the flight continues.

Extended data

flight attitude

1. An airplane flying in the air is different from a vehicle moving on the ground, and it has various flying postures.

2. The flight attitude determines the motion of the aircraft, which not only affects the flight altitude, but also affects the flight direction. When flying at low speed, the pilot can judge the attitude of the plane according to the position of the horizon by observing the ground.

Air pipeline

The route of aircraft flight is called air traffic line, which is abbreviated as air route. Aircraft route not only determines the specific direction, starting point and stopping point of the aircraft, but also specifies the width and flying height of the route according to the needs of air traffic control, so as to maintain air traffic order and ensure flight safety.
