Instrumentlandningssystem

An instrument landing system (ILS) is a ground-based electronic system that provides precision guidance to aircraft during approach and landing. It consists of two main components: the localizer and the glide slope. The localizer provides lateral guidance, helping the pilot align the aircraft with the runway centerline, while the glide slope provides vertical guidance, assisting the pilot in maintaining the correct descent angle. ILS operates in the very high frequency (VHF) band and is typically used in low-visibility conditions, such as fog, rain, or snow, where visual approaches are not possible. The system is composed of a transmitter located at the airport and a receiver installed in the aircraft. The transmitter sends out signals that the receiver interprets, providing the necessary guidance information to the pilot. ILS is a critical component of modern aviation, ensuring safe and efficient landings even in adverse weather conditions.
