Howdy all. I recently switched from F1 GTN (deprecated) to Reality XP GTN 750. All seemed ok, but I recently noticed that the VNAV appears INOP. I have gone into the config settings and insured that VNAV not VCALC is selected. 
 

The GTN performs as expected with LNAV, but for me currently VNAV is INOP. I know this is not how the product works so I’m fairly confident I am doing something wrong. Any help or insight is greatly appreciated. 
 

TIA,

Vnav is advisory and not automatically initiated if that's what you are referring to?

F1 has a different implementation.. not better, just different.

Hi Bert. I’m figuring it out and now I think I better understand. Riddle me this Batman?  Does the presence of a GARMIN AP render this discussion moot?  Does the presence of a GARMIN AP make verticals path real?  Strikes me that’s what the F1 unit was simulating. Am I incorrect in my basic understanding?

F1 was faking it... even without a Garmin autopilot.

Understood but please answer the question if you can. Does having a GARMIN AP make VNAV available?  Does it enable VPATH as the Trainer itself implies?  “Approaching Vertical Trac”?

In the real airplane.. yes.

Well then since this is ALL software, not reality than surely it can be done here for our simulations of “real airplanes”. We’re not using real GTNs  Certainly the trainer supports it?

Do you have a specific airplane in mind?

non-rxp reference

Hi Bert. Nothing specific, this is for P3D v5.3 where I have a host of aircraft I used to fly, which gave me vpath which now I can’t. 100% real?  No but this is simulation and all of it is based on reality. 

So no...nothing specific. I’m just missing my old GTN and there is nothing wrong with that.

You are right, this is just software and theoretically it is legitimate in my opinion to wonder why not faking VNAV with the RXP GTN.

There are multiple reasons but the simpler one I'd say is because it would be fake. Besides, the RXP GTN is already providing all the necessary output data, the same as the real device, and the same that are needed so that an aircraft vendor could opt to fully design an autopilot system operating like its real world counterpart, using the same signals and data logic as the real Garmin devices. Some are indeed taking advantage of this on X-Plane already.

Rest assured any 3rd vendor wanting to do it right can contact me and I'll be pleased to assist and try making this an authentic implementation.

[edit] On the other hand, you might not get a fake VNAV, but you get many more than what you probably had before, like an authentic Ryan TCAD B990X device simulation (which is using in the back end our authentic TCAS II Mark 7 simulation which is passing the industry standard TSIM tests), the capability to display simultaneously, and without affecting the fps, more than just 1 view of the same GTN at a time (you can display our GTN both in the 3D cockpit AND a popup window - and actually up to 5 instances simultaneously!). You also get probably 10x more fine grained settings covering most if not any integration needs and most if not all user preferences. Let alone all the possible integration with real hardware, be it as simple as keyboard shortcuts up to authentic replicas with integrated screen, and much much more... 😉

Your opinion. Your software. You say “Fake” if you allow your GTN 750 to pass along the Garmin VPATH simulation to non-Garmin autopilots. I say it’s fake when you allow your software to shoehorn itself into any aircraft in P3D including my FSLabs A321-211 where I am now looking at your dialog box for the configuration of a Reality XP Popup Window.

Which is more fake?

It seems like you're looking for an argument.

Although I'm sorry the RXP products are disappointing you, this is not the place, and I'm not the right person to argue with.
