Thanks. Good stuff. I always land passenger jets using ILS. Been doing it for a long, long time. So I am aware of the necessity of "coming up from under" on the glide slope. I always do that. My speed when the carat starts to descend is always around 150 with gear down and full flaps, so got that covered regarding speed, I think. Once the carat begins to descend, we can be assured I am close enough to the runway.
My problem is, the carat descends from the top down, passes the midpoint and keeps descending, but the plane just keeps flying at the same altitude. It is most frustrating.
Maybe I am not checking something on or off that should be activated or deactivated? The problem with that is, that when I am landing at a runway where the ILS "works" for the plane, I don't have any problem descending the glide slope.
