ILS
Instrument Landing System- low level approach equipment at certain airports. Airports with ILS systems are indicated in bold face type in the airport listings. Though instrument approaches and departures can be made in airports without an ILS, its presence is a material benefit to the travel planner because an instrument landing system improves trip reliability as closely as possible to the level of scheduled airlines, which generally fly from airports with these facilities.
