Abstract: In the process of aircraft flight dynamics modeling and calculation, the simulation results are usually deviated from the flight real data to some extent without considering the random factors. In this paper, based on the statistical anal-ysis of the actual flight data, a modeling method of flight attitude dynamics with random excitation is studied, and the flight dynamics of aircraft is simulated and analyzed by means of stochastic dynamics. The calculation results show that the random factors have a significant impact on the response of the simulation model, and the stochastic re-sponse can simulate the flight status of the aircraft in the real environment more accurately than the deterministic case, which provides a new idea for the precise analysis of the flight attitude in the future.
