Secret Documents #53: AJS-37 Viggen Guide Update - TILS
Added 2020-11-30 11:00:02 +0000 UTCHi folks!
The TILS (Tactical Instrument Landing System) is slightly different from a standard ILS system. Unlike a normal ILS with a large array for glideslope and localizer constructed near the runway threshold, the TILS system is a single, smaller unit placed next to the runway.
The system consists of a transmitter unit on the airfield and a receiver unit mounted on the aircraft. The receiver interprets the signal from the transmitter and creates a steering command. The slight offset from the runway heading, combined with a landing waypoint (LB) set by the navigation system results in a slightly curved approach.
