Jetpilot: Thanks for your imput. It's true,as I mentiones the a/p in 727'S was very basic and requires a lot of manual work; that's what makes it so much fun. I myself am trying to attempt ILS approaches with it.l have found this feature of FSX very difficult to master, I don't want to discourage others. So far I've manage to tune in the NAV radios. But because of the nose-up attitude 727 have on approach(I can't see the runway) When I press the engage switch...Nothing happens...Lots to learn about the 727systems...yet.
