The invention discloses a safety test flight method based on aircraft unpowered forced landing capability. According to the method, a safety area is arranged and an aircraft is unpowered to safely return to the ground for forced landing in the safety area; a safety domain circle is drawn by taking the circle center coordinate of a second spiral circle as the circle center and taking the differencebetween the radius of the circle center coordinate of the first spiral circle and the radius of the first spiral circle as the radius; and the safety domain circle forms a safety domain for unpoweredforced landing from one side of one end of the airfield runway under the unpowered condition of the airplane. A problem of flight risk management and control of a test flight subject which easily causes aerial parking is solved, the aircraft can safely return to the field and forcibly land under the unpowered condition once the aerial parking special situation occurs in the area to ensure the safety of pilots and the aircraft.

    本发明公开了一种基于飞机空滑迫降能力的安全试飞方法,包括安全区域,飞机在安全区域内无动力安全返场迫降;以第二盘旋圆的圆心坐标为圆心,以第一盘旋圆的圆心坐标圆的半径与第一盘旋圆的半径之差为半径,画安全域圆;所述安全域圆构成飞机无动力情况下从机场跑道一端一边空滑迫降着陆的安全域。本发明解决了易引发空中停车的试飞科目的飞行风险管控,确保飞机在该区域内一旦发生空中停车特情,可以在无动力情况下安全返场迫降,保证飞行员和飞机的安全。
