近年来的飞行校验中,作为飞机进近着陆关键设备之一的下滑信标的下滑道结构数据明显变差,数度逼近临界值。经现场勘察和测绘,结构数据变差疑因受下滑信标保护区地形环境恶化的影响所致。文中从理论上分析了仪表着陆系统下滑信号结构的主要影响因素,并结合下滑信标保护区实际情况进行仿真评估和结构分析,探讨适合该机场的结构改善方法,以确保仪表着陆系统运行正常、可靠。

In recent years, as one of the key equipment of aircraft approach and landing, the glide slope structure data of glide slope beacons worse and worse and approached the critical value several times. According to the field survey and mapping, the variation of structural data is suspected to be caused by the deterioration of terrain and environment in the glide beacon protection area. In this paper, the main influencing factors of the glide signal structure of the instrument landing system are analyzed in theory. Combined with the actual situation of the glide beacon protection area, the simulation evaluation and structure analysis are carried out to explore the structural improvement methods suitable for the airport, so as to ensure the normal and reliable operation of the instrument landing system.
