What system uses radio beacons on the ground to aid in aircraft landing?

The Instrument Landing System (ILS) is specifically designed to assist aircraft pilots during the landing phase by providing precision guidance. This system utilizes radio beacons located on the ground to transmit information to the aircraft. It helps pilots determine the correct angle and pathway for landing, particularly in conditions of low visibility.

The key components of the ILS include localizer and glide slope signals, which work together to direct the aircraft horizontally and vertically to the runway. When conditions are challenging, such as fog or heavy rain, the ILS becomes crucial, ensuring safe landings and enhancing overall operational efficiency at airports.

While the other systems mentioned serve different purposes, they do not focus on the precise guidance needed for landings like the ILS. The Flight Control System handles aircraft operations in the air; the Ground Support System involves maintenance and preparation for aircraft; and the Traffic Management System primarily focuses on the overall management of air traffic flow, rather than specifically aiding in landing procedures.
