A non - linear dynamic model, a landing gear model and an aerodynam ic table lookup system have been developed to improve the capabilities of the flight simulator. The environment model is built by utilizing the Aerospace toolbox in SimulinkTM; the logical relations are described by the StateflowTM and the source of aerodynamic data is DATCOM. Comparative integrated model carries out the simulation of taxi, takeoff, cruising, and landing. The simulated takeoff and landing test proves the model to be usable. The nonlinearmodel almost accurately represents the actual flight characteristics of the airplane. The flight model serves as a foundation for future simulator projects.
