Abstract:

In order to investigate and develop advanced flight simulator with high fidelity and provide the simulator with actual and reliable navigation data, the data structure requirements of navigation database for the system of flight simulator prototype are presented. These requirements including the airport, runway, very high frequency omnidirectional radio range, instrument landing system, distance measuring equipment system, nondirectional beacon and marker beacon. The complete and authentic navigation data of domestic civil aerodrome is obtained by integrating the navigation database of FlightGear and FS2004 with civil aerodrome navigation chart. The transfer function of navigation data structure is built. Based on Microsoft Visual Studio.NET, the structure transfer of navigation data is implemented; the practicable data file of navigation database for the system of flight simulator prototype is generated; complete and authentic navigation database with reasonable data structure for the system of advanced flight simulator prototype is constructed. The running results of the simulator program indicate that the proposed method for exploiting navigation database is effective and feasible.
