为进一步解决空域容量的问题,加速飞行流量,减少航班延误,民航管理部门这两年采用了不少新技术,在2008年11月实施RVSM缩小航路间隔后,从2009年6月起,在中南地区各主要机场所在地的进近和塔台管制区(高度6000米含以下)试运行目视间隔和目视进近(以下简称“双目视”),缩小终端区的间隔。本文着重分 In order to further solve the problem of airspace capacity, speed up flight flow and reduce flight delays, civil aviation administrations adopted a lot of new technologies in the past two years. Since RVSP narrowed the route interval in November 2008, from June 2009 onwards, Regional and major airports in the control of the approach and tower control area (height below 6000 meters) trial operation of the visual separation and visual approach (hereinafter referred to as “double vision”), narrow the terminal area of ​​the interval. This article focuses on points
