Among all meteorological observations, the wind speed data on the surface has the greatest impact on aircraft take-off and landing (according to the flight manual: the actual wind speed over a distance of 10 meters is reported by the tower). (1) Aircraft take-off and landing: Should be carried out under as much as possible upwind conditions. Because the wind can reduce the ground speed and landing speed, it can also shorten the take-off distance of the aircraft. The upwind takeoff can produce additional air intake to the aircraft, thus increasing the directional stability and maneuverability at the start of aircraft movement. (2) Contrary to the situation when downwind, when the wind speed exceeds the specified value, there may be danger of escaping the runway or hitting obstacles. (3) In crosswind, the aircraft moves along the direction of the crosswind in addition to the forward movement. If the aircraft does not correct in time, it will deviate from the runway, and the grounded nose will be offset towards the crosswind direction, causing the aircraft to spin and other adverse consequences.
Strengthen the monitoring of the disposal of winds in the case of near-surface winds. Strengthen the normal operation of the patrol monitoring equipment. If the signal of the main equipment is found to be unstable and the data is lost, the electronic station watch operator shall be notified in time. Once the impact is reported, it shall try to find the closest The data; If the data lost for a long time, had to use the backup wind instrument data does not meet the installation requirements; Finally, if the backup wind instrument failure or emergencies, etc., only use the wind force to determine the wind direction. Abnormal conditions must be notified to the relevant department by telephone and described in words in the minutes column.
The wind direction recorder can not only be used at the airport, it is more suitable for agriculture, and the wind direction is caused by the change of air flow in the air. The appropriate wind speed will help increase the leaf area, affect the photosynthesis of plants, and promote plant growth. .
The aircraft is very important for the wind direction and wind speed. It affects the safety of passengers. When the wind direction and wind speed are not conducive to flight, navigation will be cancelled. The wind direction recorder is used to measure and save the wind direction and wind speed. At the airport, this instrument can also be used to monitor changes in the direction and speed of the wind in real time to provide a basis for flying.
