VNAV with PMS50 GTN750

Randolf

Will the new PMS50 GTN750 VNAV feature that was added in v2.2.32 work with the Duke?

Reading the change log, it sounds like it will work, so long as you have the premium version of the GTN. All of my stand-alone aircraft have WTT integrated, so I have that part covered, at least. If you learn anything, please let me know, and I will do the same. Thank you!

If you are referring to the VNAV feature in the Utilities section of the PMS50 GTN750, then the answer is YES. I use that feature in the Turbine Duke almost daily.

@slkeyser I think you're referring to the VCALC function that only calculates the TOD for you.
But there is a new feature just a few days old in the PMS GTN that can actually fly the descent using autopilot, respecting altitude constraints of your arrival and approach procedures.
Realistically I would think that the Duke's autopilot can't be controlled by the GPS for vertical navigation, but in sim it could work, if you cheat and enable AP VNAV mode either from the GTN interface or via external control bindings.
I'll give it a try.

@Randolf - You are correct. I wasn't aware of the new feature recently added. I'll be interested to see if this works for us. Thanks for the explanation.

Did anyone get this working? Do I have to be in ATT mode?

I am confused a little by this ... the Duke manual indicates that "No additional packages should be required from PMS to enable all WTT-Mode features in this aircraft". By 'all', doesn't mean everything? It seems if I want all the features, I have to buy the PMS Premium version. Is that correct, or am I doing something wrong causing me to be unable to access some features which are currently greyed out?
