摘要： The invention is about a powered airbag for planes in case of uncontrollable falling which makes the plane fall vertically with the head up. The invention includes the bonnet cover of the head 1, the hinges of the bonnet cover 17, the head cover of the plane 12, the structural frame of the head the plane 13, the container of gas-creating material 8, Valve to activate the airbag 9. There is a difference that the structural frame of the head of the plane 13 has a powered airbag 11, the flexible soft tube 10 which connects the powered airbag 11 to the frame of the head of the plane 13
