Because the flight control system is based on aerodynamics, flight mechanics and automatic control principles, the flight control system has the advantages of abstract theory, complex model, difficult recurrence and no visual teaching means, and is difficult to intuitively explain to a student in the teaching process.

The design idea of the airplane flight control simulation system is to adopt the modern advanced computer technology to carry out full-digital real-time simulation on the flight performance of the airplane and the control performance of the flight control system, and to match with real-time demonstration of instruments and visual images, the whole flight process is reflected truly and vividly. The flight simulation teaching system is suitable for teaching research of simulated flight and teaching and theoretical research of a flight control system.

Therefore, a flight control simulation system for an aircraft that can solve the above technical problems is desired.
