摘　　要：针对所需导航性能(RNP)飞行程序的虚拟现实验证问题,结合RNP飞行程序的特点重点解析了航线及RNP隧道的结构和计算方法。利用World Wind三维地理信息系统的二次开发功能,提出了一种RNP飞行程序三维可视化及模拟飞行的方法,实现了高分辨率地理环境下飞行航迹、包容区隧道的三维可视化及动态的模拟飞行。最后利用该方法对典型的RNP飞行程序进行了仿真,结果表明该方法能够方便快速地完成RNP飞行程序三维仿真,可用于RNP飞行程序的设计及验证。To validate the Required Navigation Performance （RNP） flight procedure with virtual reality technology, the structures and calculation methods of flight route and RNP tunnel were analyzed combining the characteristics of RNPflight procedure. Using the customization functions of World Wind, the methods of 3D-visualizing RNP flight procedure and simulated flight were proposed, and then the rendering for the flight track and containment tunnel in high-resolution terrain scene as well as dynamic flight simulations were implemented in World Wind. The simulation results of a typical RNP procedure demonstrate that the 3D simulation for RNP flight procedure can be achieved rapidly ,in this way. The research findings are available to RNP flight procedure design and validation system.
