Focus on the problems existed in the topologies of the traditional VAPS XT cockpit display and control, we propose the simulation of VAPS XT cockpit display and control system based on the integrated data distribution network in this paper. This simulation uses the integrated data distribution network replacing the nCom communications network. By using this method, we can separate the business logic and the data communications mechanism of the simulation modules. Therefore, each simulation module only has to interact with the data distribution network. And the data distribution network transfers data with the VAPS XT simulation software by the nCom data communications gateway. It is demonstrated that this is an efficient way to reduce the programming work of the nCom communications and improve the scalability and flexibility of the Cockpit display and control simulation system.

This paper proposed an integration development platform of avionics system based on the model-driven method, including model-driven design, simulation, realization, integration and test. Through the applications and verification of the avionics system projects, this platform used the model-driven design to solve the problems of avionics system development, such as the long development cycle, heavy maintenance work, the complicated connection of all the development phases and the no reuse of design results. It could better adapt to the current requirements of avionics systems development.
