随着我国航空运输量的增长,一些主要繁忙机场和主要航路的容量在现有的条件下日趋饱和。当遇到恶劣天气等特殊情况时,航班由于不能及时疏散、放飞,就会造成长时间延误。为了解决主要航路上的拥塞问题,满足航空运输增长的需要,减少航班延误,充分发挥现有空管的保障能力,在得到有关单位的大力支持下,经总局批准,总局空管局决定从2001年1月22日零时起,在航管雷达和甚高频覆盖的航路上,水平纵向飞行间隔由原来的150公里(10分钟)缩小为75公里(5分钟)。这样在雷达和甚高频工作正常的情况下,所有的航路飞行容量都增大了一倍。航路容量的增
As the volume of air traffic in our country increases, the capacities of some of the major busy airports and major routes become increasingly saturated under the prevailing conditions. When encountering special circumstances such as bad weather, the flight can not be promptly evacuated, flying, it will cause a long delay. In order to solve the congestion problem on major air routes, meet the needs of air transport growth, reduce flight delays and give full play to the existing air traffic control support capabilities, with the strong support of the relevant agencies, with the approval of the General Administration of Customs, the Administration of Air Traffic Control decided in 2001 From January 22, at 0:00 on January 22, the horizontal longitudinal flight interval has been reduced from 150 kilometers (10 minutes) to 75 kilometers (5 minutes) on the air traffic radar and VHF-covered routes. This has doubled the capacity of all routes on all routes with radar and VHF working properly. Increase in route capacity
