Hi 411A
being quite a lot older, and have successfully used dive/drive over many years
I bet you're not older than me! I'm now using CDA NPA with FMS (FMGS) generated vertical profile - something my dear old TriStar couldn't do. If your FMS could provide an accurate VNAV profile - I bet you'd use it too. It's PFM (well almost).
However, if you can't do VNAV approaches I can see the advantage of the extra time you'd have at MDA up to your MAP, and the brilliantly clever DLC giving instantaneous change in VS.
Horses for Courses.
