本文利用近五年虹桥机场AWOS的跑道视程(RVR)和跑道灯强度数据,分析了低跑道视程与跑道灯光强度变化的相关性。研究表明,RVR1A序列与RVR10X序列分别与对应的跑道灯光变化的相关系数为0.203、0.838;初始跑道视程在600-800 m区间时抬升幅度基本在30%-40%,而当初始跑道视程低于600 m或者大于1 000 m时,增强跑道灯光对跑道视程影响不大,因此只有当初始跑道视程在600-800 m区间时有必要提升跑道灯光。
Based on the AWR and runway light intensity data of AWOS at Hongqiao Airport in recent five years, this paper analyzes the correlation between runway visual range and runway lighting intensity. The results showed that the correlation coefficient between the RVR1A sequence and the corresponding RVR10X sequence was 0.203,0.838. The initial runway range of elevation ranged from 30% to 40% at the range of 600-800 m. When the initial runway visual range Under 600 m or over 1000 m, enhanced runway lighting has little effect on runway visibility, and therefore it is necessary to enhance runway lighting only when the initial runway is in the 600-800 m range.
