Ils glide slope range. 15 MHz to 335. ILS (Instrument Landing System) is a ground-based radio navigation system that guides an aircraft safely to the runway during landing — especially in low visibility. The glide path radiates its signal only in the direction of the localizer front course. Localizer as component of an ILS (KMEZ runway 27, Mena, Arkansas) Emission patterns of the localizer and glide path signals An instrument landing system localizer, or simply localizer (LOC, [1] or LLZ prior to 2007 [2]), is a system of horizontal guidance in the instrument landing system, which is used to guide aircraft along the axis of the runway. B. Glide-slope The ILS GS aerials are normally located on the aerodrome; they transmit two narrow intersecting beams, one slightly below the required vertical profile and the other slightly above it which, where they intersect, define the "on GS" indication (see Figure 2). 00 MHz radiates its signals in the direction of the localizer front course Jan 10, 2026 · A glide slope provides vertical (up/down) guidance toward the runway touchdown point, usually at a 3° slope. Instrument landing system Diagram of an instrument landing system (ILS) approach In aviation, the instrument landing system (ILS) is a precision radio navigation system that provides short-range guidance to aircraft to allow them to approach a runway at night or in bad weather.
