Instrument Landing Systems (ILS)

Thales ATM ILS systems assist the majority of airplanes to land at airports around the world, proving Thales ATM's reliability and safety. Thales ATM offers more ILS engineering, manufacturing and field support of ILS equipment experience than any company in the world. Fully compliant with all ICAO Annex 10 and U.S.A. FAA requirements, the ILS family of compatible products span all categories of ILS, from single channel, single frequency Category I (CAT I) landing operation to the most demanding CAT III installation.

Thales ATM Cat I, II and III systems give precision navigational information to pilots in varying weather conditions. The Thales ATM Cat I system assists pilots when visibility is as low as 800 meters (1/2 mile), with a decision height of 200 feet. Cat II systems allow landings with visibility of 400 meters (1/4 mile) and a decision height of 100 feet. Cat III systems allow planes with 300 feet visibility to land safely, guided only by the Thales ATM ILS

All ILS categories operate with the same three major subsystems.

Thales ATM ILS supplies critical approach and landing information to pilots through three major subsystems: The Localizer, Glideslope and Marker Beacons.
