The invention provides a foresight terrain avoidance alarm method based on aircraft climbing performance, which comprises the following steps: calculating a maximum climbing rate and a track inclination angle, calculating a foresight terrain avoidance alarm, obtaining a suggested climbing rate output value, and accumulating in multiple flight tests to obtain temperature, weight and height information and corresponding climbing rate and track inclination angle data. Aiming at the influence of the flight height, weight and temperature of the airplane in the climbing process on the flight performance of the airplane, the foresight terrain avoidance alarm algorithm based on the airplane performance is adopted in combination with the flight data of the height, weight and temperature of the airplane, and the method is simple, easy to implement, high in real-time performance and high in reliability. The method can effectively reduce the false alarm rate, improves the performance of a ground proximity alarm system, and effectively guarantees the flight safety of an airplane.
