Currently,the instrument flight procedure is usually presented by planar graphs and tables.In this paper,a visual flight program verification method is put forward based on the three-dimensional (3D) geographic information system WorldWind.A 3D virtual environment was set up in WorldWind.Then,the airport anchor points,track and navigation station coordinates and other key parameters were entered,and processed by 3D coordinate transformation and interpolation.By using the data obtained,an instrument flight procedure was generated in the 3D environment,and flight simulation was made.Experiments show that,the proposed system can complete the 3D visualization of instrument flight procedures rapidly,and has good expansibility,which can be used for the auxiliary design and verification of instrument flight procedures.
