These factors affect the taxiing distance, ceiling, load and fuel consumption of aircraft during takeoff and landing. Experts pointed out that the accurate landing and high-altitude flight of aircraft can not be separated from the opening pressure and standard atmospheric pressure, and the temperature has a great influence on the load of aircraft and the taxiing distance during take-off and landing. With the increase of air temperature, the air density becomes smaller, the generated lift becomes smaller, the aircraft load decreases, and the take-off taxiing distance becomes longer.

2. the wind.

Wind shadow affects the distance and time of takeoff and landing. According to experts, most planes take off and land against the wind, and the crosswind cannot be too strong, otherwise they cannot take off and land. When airlines fly, downwind reduces fuel consumption and shortens flight time, while headwind is the opposite. However, wind shear is easy to cause aviation accidents, accounting for about 20% of aviation accidents. This is caused by the discontinuity of the wind, which has the characteristics of short time, small scale and high intensity.

3. Cloud.

The low-altitude clouds over the airport will make the pilots unable to see the runway clearly, which will directly affect the take-off and landing of the aircraft. The most harmful cloud is convective cloud. Once the plane enters, it is easy to be impacted, causing instrument failure and fuel tank explosion, or causing strong bumps and icing, resulting in control failure and flight accidents.

Aviation safety mainly includes:

1. flight safety: during the operation of the aircraft, there will be no accidents such as casualties and aircraft damage caused by flight or other reasons.

2. Aviation ground safety: the safety of production activities around the apron and flight area where aircraft operate. Prevent aircraft damage, casualties of passengers and ground personnel, and damage to various ground facilities. At the same time, it also includes the safety of aircraft maintenance, cargo and service loading and unloading, aircraft refueling and other activities, as well as the safety of military aircraft weapons and ammunition.

3. Safety guarantee: prevent illegal interference activities that affect the normal operation of aircraft and directly endanger flight safety, and prevent ground weapons from being fired by mistake.
