JayG: I'm in the same boat as you right now with thew 727. Auto approaches and ILS's...
Today I managed my first ILS approach, I'm not pround of it because I landed faaaaaaaaaaar away from the runway That is the plane began it's auto descend too soon. The capture of the ILS heading was straight on. But the maintaining of altitude,unless I'm doing/ expecting something (?) was way too soon. It landed the plane a good 5 miles out in front of the runway????? :-/
