The Outer Marker is typically located at what distance from the runway threshold?

Explanation:
In an ILS approach, markers along the localizer provide distance cues on the final approach. The Outer Marker marks a point farthest from the runway where you’re still on the published localizer path, giving you a timing cue before you descend on the glide slope. It is typically located about 4 to 7 nautical miles from the runway threshold, hence the correct distance. The marker is usually indicated by a blue light and the distinctive “OM” Morse identifier.
