The invention provides a short-distance take-off and landing flight method depending on attack angle lift force, relates to the technical field of aircrafts, points out the essence that the attack angle lift force comes from air acceleration, and provides a calculation method and characteristic indexes of short-distance take-off and landing flight depending on the attack angle lift force. The flight principle, the trimming mechanism and the control method of the flat-plate-wing aircraft are systematically elaborated, the dynamic mechanical analysis process is simplified, the aerodynamic layout design key points of the A-wing aircraft are summarized, the flight theory of short-distance take-off and landing depending on the attack angle lift force is provided, and accordingly the two-dimensional maneuvering characteristics and the market application prospect of the A-wing aircraft are analyzed. The direction is pointed out for aerodynamic layout planning and preliminary design calculation of the A-wing aircraft; according to the method provided by the invention, theoretical analysis, configuration design, parameter calculation, take-off and landing modes and flight control of the A-wing aircraft are covered, and a complete technical scheme is formed.
