The stock ILS approaches at KLGA appear to be messed up. The ILS approach to runway 13 picks up the localizer backcourse to runway 31, so it appears as a backcourse with no glide slope. I fixed that by moving the 31 localizer to dummy runway at some other location. That's fine because the real world KLGA does not have a localizer for runway 31. Now my problem is that the ILS to runway 22 is picking up the backcourse and identifier to the ILS for runway 4. This is true for both FS9 and FSX. Two questions: with ILS at both ends of a runway using the same frequency, how doe FS distinguish which is in use. The other question is how can I fix the situation described above. BTW, I've tried unchecking the backcourse checkboxes, but that doesn't fix the problem. I'm about to pull out what is left of the hair on my head over this!
