so thus once I hit the localizer with the ils freuency about say 25 miles out what is the difference between auto glide slope and main glide slope on the ap.? wHAt is the sequence here withe the glide slpe, should I just hit main g/s when the triangle on the adf is just above the middle ?

by the way I know we are getting close cause I recently did a couple of il landing unfortuntately since I was a bit of course took over manually. I love this plane and its my favorite all time so help me out, we are defintely making progress..
