所需性能导航的飞行模拟机视景仿真实现

Required Navigation Performance Flight Simulator Visual Simulation Realization

为实现适合所需性能导航(RNP)程序训练的飞行模拟机机场视景仿真数据库,从拉萨机场对RNP飞行程序训练的实际需求出发,研究RNP程序,对地形网格算法进行人为干预,引导地形生成需要的效果和精度,满足飞行验证和训练的要求,实现机场三维全态仿真与RNP程序的结合,研究结果可推广到其他类似机场的视景仿真开发。

The purpose of this study is to achieve the required navigation performance（RNP） training program for the flight simulator airport visual simulation database. From a specific requirement for Lhasa airport RNP flight procedures training the RNP procedures are studied, the terrain mesh algorithm is processed by human in tervention. The terrain generation effectiveness and accuracy are guided to meet flight verification and training requirements, realize the combination of 3D simulation of airport and RNP program. Results of this study can be generalized to other similar airports visual simulation development.
