What is the main task of the air force bird repellent team?

If the "invisible wings" to ensure the safe flight of aircraft do not control and guide the birds, it will affect the flight safety of aircraft. For example, when a bird enters the turbine engine room of an aircraft external engine, it will damage the turbine blades, which will lead to engine failure and even serious air crash. In addition, there are many precision instruments on the plane, especially some exposed instruments. Once they are hit by foreign objects in flight, the consequences are unimaginable. Even if birds collide with the front windshield of an aircraft in the air, it will pose a threat to the safety of pilots and aircraft. 30 minutes before the take-off and landing of 15 aircraft is the main working time of the bird repellent team, and the range from 300 meters to 500 meters around the center of the aircraft is the key bird repellent area of the bird repellent team. "This range is a buffer zone for the take-off and landing of aircraft. "In addition to the bird-repelling operations in specific areas required by relevant airport departments, the working hours of the bird-repelling team mainly change with the changes of flights and flight plans.
