摘　　要：仪表着陆系统(instrument landing system,ILS)主要由产生水平引导的航向信标以及产生垂直引导的下滑信标组成。下滑道曲面是下滑信号由下滑天线辐射出去,经过地面反射和空间调制形成。下滑道曲面的倾斜程度会直接影响下滑道的特性。本文从下滑道曲面的原理入手,分析和研究产生倾斜的原因,结合飞行校验的检查方法、标准及飞行校验实例,提出解决该类问题的方法和建议。The Instrument Landing System(ILS)is mainly composed of a localizer that generates horizontal guidance and a glide slope that generates vertical guidance.Glide path surface is glide slope signal radiated by glide antenna and formed by ground reflection and spatial modulation.The inclination of glide path surface will directly affect the characteristics of glide path.Starting from the principle of glide path surface,this paper analyzes and studies the causes of the inclination,and puts forward methods and suggestions to solve this kind of problem based on flight inspection methods,standards and examples.
