摘要
文章对成都双流国际机场气象自动观测系统中的气象光学视程(MOR)与跑道视程(RVR)的相关性进行了分析研究,使用阿拉德定律和柯西密德定律对不同时间段的MOR与RVR值的差异进行对比并得出结论:在白天时段,MOR与RVR大致相同,在夜晚时段对采用阿拉德定律计算出的RVR估值进行报告;在下午至黄昏时段,同时使用阿拉德定律和柯西密德定律计算,选用较高的值作为RVR估值,并检验数据的延续性。研究结果可以为RVR估算的研究提供新的参考思路和解决方案,为飞机的飞行安全、航空公司的经济效益以及管制人员的保障工作等提供更有效和更精准的参照。
This paper analyzes and studies the correlation between the Meteorological Optical Range(MOR)and the Runway Visual Range(RVR)in the automatic meteorological observing system of Chengdu Shuangliu International Airport.The differences between the MOR and the estimated RVR in different time periods are compared using Allard's law and Koschmieder's Law,and the conclusion is drawn:during the daytime period,the MOR is roughly the same as the RVR,and during the nighttime period,the RVR estimation calculated using Arad's law is reported.For the afternoon to dusk period,both Arad's law and Cauchy's law should be used for calculation,and the higher value should be selected as the RVR valuation,and the continuity of the data should be tested.The research results provide a new reference idea and solution for the research of RVR estimation,and provide a more effective and accurate reference for the aircraft flight safety,the airlines economic benefits and the security work of controllers.
