TCU,
I think you are right about not getting an EADI. A bit of dreaming on my part, along with looking at what it can have (pic's of KLM's cockpit) v's what it is getting.
The Vpath is like you say, not linked to the AP. I should have elaborated more. Good for a VOR/DME etc. profile. I don't see the wheel being re-invented when it comes to the descent profile for most guys.
Regards
