Instrument Landing System (ILS)
The Instrument Landing System (ILS) is an advanced electronic system that enables ILS-equipped aircraft to safely land on runways under low visibility conditions by providing accurate horizontal and vertical guidance. The system is based on radar technology and is capable of guiding aircraft to a specific runway, assisting pilots to execute a precision instrument approach procedure.
The ILS system provides both horizontal and vertical guidance to an aircraft, helping the pilot to line up and descend to the runway at a controlled rate of descent. The horizontal guidance is provided by the localizer system, which provides accurate information to the pilot on the aircraft’s position relative to the runway’s centerline. The vertical guidance is provided by the glide slope system which enables the pilot to maintain a precise descent rate until reaching the runway’s touchdown point.
The ILS system is an essential technology that modern aviation relies on to ensure safe and efficient landings in low visibility conditions. It provides pilots with the ability to conduct precision instrument approaches, which allow them to land safely even when clouds are as low as 200 feet.
