The invention provides an aircraft reachable area estimation method. The aircraft reachable area estimation method comprises the following steps: simplifying the flight range of an aircraft into a straight section before turning, a turning section and a straight section after turning, wherein the flight range of the straight section before turning, the flight range of the turning section and the flight range of the straight section after turning should meet the following inequality; according to the geometric relationship of the flight path, obtaining the end-of-flight coordinates of the aircraft; and according to the obtained flight tail end coordinates, traversing the flight path of the aircraft, and obtaining a scattering set of the tail end points of the aircraft, so that the reachable area of the aircraft can be obtained. According to the method, the reachable coverage area of the aircraft can be rapidly estimated only through the basic parameters of the aircraft, the rapid estimation of the reachable area of the aircraft in the initial stage of an aircraft design scheme is achieved, the calculation complexity is reduced, and the calculation time is shortened.
