摘要： 为了对京沪区域导航平行航路的DME／DME导航性能进行分析，本文在国际民航组织的DME／DME导航精度计算方法的基础上，考虑我国地理坐标系的特点，修正了导航精度计算方法。借助Maplnfo工具软件，确定了京沪区域导航平行航路的DME／DME定位有效区域。结果表明在京沪区域导航平行航路上，能够实现DME／DME有效区域多重覆盖，其导航精度在3，2海里以内，满足RNP4的精度要求。

Abstract: In order to analyze the navigation performance of parallel Area Navigation(RNAV)route between Beijing and Shanghai，this paper develops an improved navigation accuracy algorithm based on calculation method of DME／DME navigation accuracy of international civil aviation organization(ICAO)and characteristic of coordinate system of our country．It determines available area of DME pair by the help of Mapinfo software．The result is that parallel(RNAV)route between Beijing and Shanghai has a possibility of being covered by the available area of multiple DME pairs，and navigation accuracy can be within 3.2 nautical mules，which meets the accuracy requirement of RNP4．

Key words: area navigation, navigation performance, parallel routes
