摘要: 为提高RNAV(区域导航)精度,采用空间向量分析,导出了FANS(国际民航组织倡导的新航行系统)航线的初始航线角和航线距离计算公式;用辛普森自适应算法进行了仿真计算,并与大圆航线的计算结果进行了比较.结果表明,当航程小于1 000 km时,对于近EW走向的航线,FANS航线比大圆航线长约0.35%;而对于近SN走向的航线,FANS航线比大圆航线短约0.24%.Abstract: To improve the precision of area navigation,the formulas of calculating the initial course and route distance of an FANS(the future air navigation system) route was derived through spatial vector analyses.A simulation calculation was made by the Simpson numerical integral,and the simulated results of the initial course and route distance were compared with those based on the great circle route.The research shows that if the distance of a nearly east-west route is less than 1 000 km,the FANS route is approximately 0.35% longer than the great circle route,but if the distance of a nearly south-north route is less than 1 000 km,the FANS route is about 0.24% shorter than the great circle route.
