| 摘 要： | 为准确计算基于WGS-84坐标的RNAV进近程序航路点坐标和航迹引导参数,提供精密RNAV导航数据,降低RNAV进近系统误差,提出了实测跑道入口WGS-84坐标,然后沿跑道中线外推各航路点WGS-84坐标的计算方法。采用Gauss平均引数法对各航段的航线角及航段距离进行了反算,以验证外推航路点坐标的计算精度。通过西南地区某机场＂T＂型RNAV进近程序的设计及飞行验证,该方法可推广到其他机场的RNAV进近程序设计。

| Abstract: | In order to calculate RNAV approach procedure waypoints WGS -84 coordinates and track guiding parameters, the calculating method of extrapolating waypoints coordinates according to runway threshold WGS - 84 coordinates is brought forward in this article. The course and distance of each approach procedure leg are calculated with Gauss mean argument. The correctness of the calculating method is proved with the example of ＂T＂ RNAV approach procedure design of certain airport located at southwest China,it can be applied to other airport RNAV approach procedure design. |
