根据世界气象组织规定,每天北京时间07:15和19:15,全球固定探空站必须在同一时间准时进行高空探测,如遇特殊原因,放球可推迟,但不能超过正点的1.5小时。昌都地区气象局是国家确定的基本气象观测站,也是世界气象组织在全球范围内的国际气象资料交换站。因此,该地区无权停止施放探空气球或者改变施放时间。而昌都是拉萨航带线上极其重要的一个导航台,按正班时刻,早晨从成都起飞到拉萨的几个航班都要受到很大的影响。如何解决这一问题,不仅关系到航空公司和旅客的安全及利益,也是我们空管部门服务态度、质量和效益的一个重要指标。 2001年9月25日,执行成都-拉萨航班任务的CXN4401于北京时间06:44从双流机场起飞,52分钟
According to the provisions of the World Meteorological Organization, every day at 07:15 and 19:15 GMT, the global fixed sounding station must conduct aerial exploration on time at the same time. For special reasons, it may be postponed, but it can not exceed 1.5 hours of punctuality. The Meteo-Meteorological Bureau of Chamdo Prefecture is a country-defined basic meteorological observatory and a meteorological organization for global meteorological data exchange within the world. As a result, the area has no right to stop the release of the sounding balloon or change the casting time. However, Changdu is an extremely important navigational airstrip on the Lhasa navigation belt line. According to the official timetable, several flights from Chengdu to Lhasa in the morning have to be greatly affected. How to solve this problem is not only related to the safety and interests of airlines and passengers, but also an important indicator of the attitude, quality and effectiveness of our air traffic control services. On September 25, 2001, the CXN4401, which is responsible for the Chengdu-Lhasa flight, took off from Shuangliu Airport at 06:44 Beijing time for 52 minutes
