Abstract:

Navigation database is necessary data sources for flight management computer which can be used for navigation calculation,auto-tuning management of the navigation station，and the real-time location of aircraft,etc.To develop high-fidelity flight simulation visual system，a navigation database based on World Wind is designed and implemented. This database includes the information about airports,runways,instrument landing system,and distance measuring system,etc. So the global navigation data can be queried，modified and displayed，also the flight plan can be controlled and displayed. Finally all information will be displayed in World Wind by three-dimension. Digital elevation data and high-definition remote sensing images acting as visual model,a flight simulation visual system based on the database is completed by the WW platform combined with a flight simulation plug-in.

Key words: navigation database, FMC, World Wind, flight simulation visual system
