IFR hold short line at uncontrolled airports?

Yes, they can adjust the localizer width. An example is listed below for
Billings MT ILS. (BIL) If you scroll through the data, you'll notice the
LOC width is listed as 3.34 degrees under AFIS DATA.

The glideslopes are as they are all positioned to bring you to the same

spot

on every runway. The localizer is sited so it is a certain width at the
approach end of the runway, therefore they will move the localizer antenna
closer to or farther away from the departure end of the runway to achieve
that.


They can't "focus" or "tighten" the signal for longer runways???
