Wind shear is dangerous to flight safety. First, it may cause the airspeed increased and decreased. When we fly from tailwind into headwind, the airspeed will be increased and when we fly headwind into tailwind, the airspeed will be decreased. Second, it may cause the aircraft to lose altitude, so the aircraft is difficult to control.
