In order to overcome the defects in the prior art and solve the problem of real-time identification of the flight action of an aircraft, the invention provides a flight action real-time identification method which can identify the flight action of the aircraft in real time based on the flight parameter data obtained by real-time transmission. According to the method, the straight line and curve feature judgment of a flight track of the aircraft is attributed to the judgment of module values and angles of displacement dot products and cross products at different time points, the problem of judgment of straight movement and steering of the track is simply solved, and the calculation method is visual and efficient. Aircraft flight actions are divided into single flight actions and composite flight actions, the problem of multi-level judgment of flight action recognition is solved, orderliness is clear, and modeling is easy. Through the combination of a plurality of single flight actions and composite flight actions, various flight actions can be deduced, the method is suitable for identification of any flight action, and expansion of flight action types is facilitated. The flight action recognition method is clear in concept, strict in design, complete in algorithm, visual in process and simple and convenient to model, the real-time recognition of the flight actions can be achieved, and the flight control capacity and the flight evaluation capacity are remarkably improved.
