The instrument landing system (ILS), in its present 90/150 Hz format, had its beginnings in the United States and England during the years from 1939 to 1945. Since then, it has served the aviation community worldwide. There have been many improvements to cope with ever increasing traffic, crowded airports, and difficult siting problems. This article investigates whether the system should be replaced with newer technology, or upgraded.
