Abstract

The glide path (GP) is an integral part of the Instrument Landing System (ILS), working in conjunction with the onboard receiver to provide glide guidance information for aircraft approaching and landing, operates in the 328.6 to 335.4MHz ultra-high frequency range, signal transmission mainly relies on the reflection of the protected area in front of the antenna. However, the mountain ahead has caused problems with the GP at multiple airports. The revised MH/T4003.1-2021 in 2021 is based on the original 2014 version, added obstruction requirements for obstacles ahead. Through computer modeling and simulation, this article conducts simulation analysis on the influence of the mountain in front of the GP on the glide slope structure and glide clearance under different obstruction angles, proposes a solution for the site selection and signal optimization after construction of the GP.
