本文以某机场"航向信标前航道17～25 n mile段内左侧(+)3°以外信号场强超限"现象为例,从行业标准规范、设备特性、地形障碍物、电磁仿真和飞行校验等诸多方面展开了分析,探究了航向信标覆盖扇区内信号场强超限的原因,以期飞行更加安全.
Substandard Situation Analysis of Minimum Field Strength of Localizer
Taking a certain airport as an example,focusing on the phenomenon that the signal field strength from 17 nautical miles to 25 nautical miles between 3 degrees and 10 degrees on the left side from the front course line is too weak,this paper studies the influencing factors of signal coverage,such as industry standard and specifications,equipment characteristics,terrain and obstructions,electromagnetic simulation,and flight inspection,etc.,and explores the causes of the signal field strength below minimum operational performance standards within the coverage sector of localizer path,in order that airplanes can fly more safely.
