The reason for the delay of the plane

The reasons for the delay of the plane are bad weather, air traffic control and mechanical failure.

Influence of bad weather: The weather causes include many situations, such as the weather conditions at the departure airport are not suitable for takeoff, the weather conditions at the destination airport are not suitable for landing, or the visibility is extremely low, there is a thunderstorm area near the airport's take-off and landing, or the weather conditions on low-cloud flight routes are not suitable for flying over. , will delay the plane.

Air traffic control: China's airspace is different from other countries, with stricter control. What is air traffic control? That is to say, in order to avoid traffic jams during navigation, with the development of civil aviation, there will be more and more planes in the sky, but the ground support facilities, such as communication and navigation equipment, can't keep up, and then the controllers' working ability is limited, which will cause aircraft delays.

Mechanical failure: this also reflects the particularity of aircraft as a means of transportation. If the automobile machinery breaks down, you can park in the emergency lane, but the plane has no emergency lane in the sky. After all, the plane can only fly by flight, so any mechanical failure of the plane is not allowed to fly. Need to check again, after troubleshooting before flying.

Take-off and landing of aircraft

The takeoff of an airplane depends on the lift generated by the relative movement with the air, and the lift depends on the relative speed between the airplane and the air, not the relative speed between the airplane and the ground. If you take off against the wind, the taxiing speed of the plane is opposite to the wind speed, and the relative speed between the plane and the air is equal to the sum of the two.

Landing is similar to taking off. In the process of landing, it is necessary to keep enough lift while slowing down to ensure the plane can descend smoothly. When landing against the wind, the aircraft can get the required lift at a low speed, thus reducing the relative speed between the landing moment and the ground, thus shortening the taxiing distance. When landing with the wind, the relative speed between the plane and the ground is greater than that when landing against the wind, and the same lift can be obtained.
