The Instrument Landing System (ILS) - A Review

Abstract

The primary objective of this paper is to emphasise and elucidate on basic information about the Instrument Landing System (ILS); which happens to be a high precision & accuracy-based radio navigation equipment. It is primarily a ground-based system which utilises an amalgamation of radio signals wherever they are received by airports and airlines around the world; providing both lateral and longitudinal guidance of an approaching aircraft, landing on a runway in atmospheric meteorological conditions. The purpose of this paper is to delineate the architecture of the ILS, its composition, installation, components etc.
