Temporarily disabled ILS range tweaking, until we come up with a
better scheme.

While it's true that the actual ILS indications are unreliable when
far off the approach path, the ILS is not out of range -- you can
still ident it (an essential part of any approach procedure), and the
indicator will usually be doing something, however bizarre.  The
current scheme did not allow the user to ident the ILS until
practically on the approach path.
