Without considering random factors, the simulation results are usually deviated from the real flight data to some extent in modeling and calculation of aircraft flight attitude dynamics. In this paper, based on statistical analysis 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 random factors have a significant impact on the flight attitude, and the stochastic response of the simulation model considering random factors can more accurately simulate the flight status of the aircraft in the real environment than the deterministic response, which provides a new idea for precise analysis of the flight attitude in the future.
