一、引言云、能见度和风是飞行活动最主要的三个气象条件。在日常飞行活动中,一般以云和能见度为标准。“复杂气象飞行”与“简单气象飞行”指的就是云和能见度的条件,为此各地空管部门根据当地的气象特征和设备情况,制定出各自的天气运行标准。为了加强气象保障工作,民航总局曾发布各种文件,要求各地确保气象情报的及时发布,加强气象安全工作。
I. INTRODUCTION Clouds, visibility and wind are the three most important meteorological conditions for flight operations. In daily flights, clouds and visibility are generally the norm. “Complex Meteorological Flights” and “Simple Meteorological Flights” refer to the conditions of clouds and visibility. Therefore, the ATC departments at all levels work out their own weather operation standards according to the local meteorological features and equipment. In order to strengthen the work of meteorological support, CAAC has issued various documents requiring all localities to ensure timely issuance of weather information and to strengthen meteorological safety.
