| 摘 要： | 主导能见度是航空活动能否正常进行的重要标准之一。伴随我国通用机场建设,主导能见度的自动观测具有重要的实际意义。本文使用中值法、图形比例法和均值法3种方法,利用机场现有多套能见度传感器进行主导能见度自动观测,并使用3种方法研究分析了天津、大连、海拉尔、成都和重庆5个机场2014年12月10日起连续100天的07:00和19:00 2个时间点的多能见度传感器测量值。结果表明:相比于中值法和图形比例法,均值法具有更小的观测偏差;观测原理和方法、能见度传感器数量、地区气候差异和观测位置差异是影响主导能见度自动观测数据质量的主要影响因素。

| Abstract: | Prevailing visibility is an important parameter of normal civil aviation activities. It has obvious practical significance along with the increasing constructions of general aviation airport. In consideration of the existing visibility meters in a single aerodrome, we use three methods to calculate the airport prevailing visibility: median method, graph proportion method and averaging method. We use the existing multi set visibility sensors at the airport to conduct automatic observation of prevailing visibility and use the three methods to study and analyze the multi visibility sensor measurements at daytime and nighttime in Tianjin, Dalian, Hailar, Chengdu and Chongqing for 100 consecutive days. After qualitative and quantitative analysis and comparison, the averaging method is proved to have less measuring error than that of the median method and graph proportion method. The differences in observation principles and observation methods, the number of visibility meters, regional climate, and observation locations are the main factors affecting the data quality of prevailing visibility. |
