Worrying about GS service volume seems off-scale unimportant relative to other issues. For starters, Stansted has a reversible ILS. The code to handle reversible ILSs in FG has been broken for years, and actually got worse recently. The code to make it possible to fly at airports with

I had a squawk here from a (real) King Air pilot because on an ILS approach, our glideslope indicator doesn't become active/in-range until about 7-8 miles out. Beyond this range the indicator just stays centered at zero. With a standard 3 degree glide slope, 7 miles out equates to about 2000'

Consulting my course material for passing the ATPL tests in Europe I read that the glide path is required to be usable up to a distance of 10 NM (which I interpret from the touch down zone not the distance to an DME that may or may not be at destination). This distance should be valid +-8
