Abstract:
In order to improve the visual feelings and simulation fidelity of Control and Display Unit(CDU) in flight simulator research, based on embedded PC104 CPU and 8255 programmable interface card, this paper designs membrane keyboard hardware circuit and keyboard code scan program and realizes the high fidelity simulation for CDU keyboard. Meanwhile, the CDU simulation page is constructed by utilizing object-oriented simulation technique. It successfully tackles pages system’s tiresome generation and management problem. Simulation experimental results show that the method realistically implements routing data and performance parameters input and display in flight simulation.
