The civil aircraft with fly-by-wire control system equipped with two passive side-sticks was chosen as the research subject. A flight simulation system was built based on the visual flight system technology. The self-writing key program is available for various civil aircraft models, and it is creative and functional. The part of visual flight simulation based on the Flight Gear is of realistic scene and it achieves the goal of real time input of two handling sticks. The system fills the gaps in the study of the fly-by-wire equipped with two passive side-sticks in the civil aircraft in our country. The simulation results show that: The simulation system can describe and record the flight process effectively. The system has clear structure, good expansibility, fast operation and the advantage of easy to use. It lays foundations for the further study and application and provides a favorable developable visual simulation platform.
