针对目前仪表飞行程序多采用平面图和数表方式给出的不足，提出一种结合三维地理信息系统WorldWind的可视化飞行程序验证方法。首先在WorldWind中搭建虚拟化三维环境；然后输入机场定位点、航迹和导航台坐标等关键参数，通过三维坐标转换和插值等方法进行处理；最后根据所得数据在三维环境中生成仪表飞行程序，并进行飞行模拟仿真。实验表明，该系统能够方便快速地完成仪表飞行程序的三维可视化且具有较好的扩展性，可用于仪表飞行程序的辅助设计及验证。

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.
