The Instrument Landing System (ILS) uses marker beacons to guide aircraft during landing approaches. The Outer Marker (OM), Middle Marker (MM), and Inner Marker (IM) are positioned at specific distances from the runway threshold.
The Outer Marker is typically located 3 nautical miles from the runway threshold, while the Middle Marker is at 400 yards. The Inner Marker is positioned 1,000 feet from the runway threshold.
