SV2003,
This sounds like a continuation of our previous thread about adding ILS..............
Most glide slopes that I have seen in AFCAD are located at the far end of the runway with a 3-degree projection angle. This might not work for all airports - sometimes it's a matter of trial and error to figure out what works best. The best way of testing the glide slope is to tune the ILS frequency in NAV1 and use slew mode to see if the angle is appropriate.
Adding ILS to a runway in FSSC as we discussed will have no effect on the behavior of AI traffic, as it is an addition to the scenery rather than the AFCAD file. How an AI aircraft behaves on approach is a function of its .air file. Also keep in mind that there are a lot of aircraft out there that aren't designed for AI traffic use!
Good luck!
Erik
