China okays use of WGS-84

Various national departments in China have given the go-signal for the Civil Aviation Administration of China (CAAC) to use the World Geodetic Survey 84 (WGS-84) starting July 1. The CAAC will gradually transfer to the new WGS by the International Civil Aviation Organization in the next several years to promote flight safety. The coordination system will facilitate the full implementation of new technologies, such as satellite navigation and RNAV; the functioning of aircraft airborne equipment; solving safety operation problems of airports with complex terrain in west China; and improving the use of limited airspace resources in east China. The CAAC will soon develop preparation work for the WGS-84. The CAAC will gradually transfer geodetic data to the WGS-84 coordination system, and settle the issue of military and civil aviation to use coordination data together.
