Abstract: Some modeling tools can't design simulation instruments efficiently and conveniently such as OpenGL, etc. A cockpit display development tool of IData was worked in which has graphical user interface and could develop a system easily and rapidly. IData is a method of designing maps and pictures, it can respond variables of application and controlling events in real time and develop graphical interface by clicking on the menu. So IData can reduce the time of graphic development and integration in simulation. In order to render maps in real time, IData used a powerful graphic editor to model for instruments, and used ‘byte code' format to keep the modeling files for instruments. Combining with IData and VC++ could model fast and efficiently. EICAS system of fight simulator was developed in the two tools. The practice proves that the system is developed quickly and efficiently. It makes the software convenient to be extended and maintain again. The system is praised by the most of the pilots.

Key words: IData, EICAS system, simulate, emulator, software
