I recently bought the GTN 750 and the new PC-12 from Carenado for X-Plane 11, where the GTN 750 is nicely integrated into the panel when activated. In the PC-12 cockpit there is the second standard GNS 530 unit, which is only partly functional in this setup: It seems that the position of the plane is not propagated to this unit, only the radios (COM and NAV) are usable.

So the question is: Is this function limitation of the (second) original GNS 530 unit caused by the way the RXP GTN is integrated into X-Plane or can the second GNS 530 unit be made fully functional by proper programming or configuring of the cockpit? If so: what must be done?

Hi Greg,

Is this the default X-Plane GNS or a custom one?

There is nothing preventing the default running along side the GTN, but I can't tell for any custom coded GPS though. Could this be the PC12 setup is 'failing' removing the 530 when used with the GTN (i.e. it was not designed for the two to coexist)?

Hi RXP

Please try this: Start a new flight in X-Plane with the default Cessna 172, the model with the default GNS 530 as GPS1 and the default GNS 430 as GPS2. Now activate one of the RXP GTN 750 units from the menu (1 or 2). At this time you shuld have 3 GPS units active. Now take off , start flying and see how the GPS units operate.

For me: GTN 750 and default GNS 530 (GPS1) work as expected. But the default GNS 430 (GPS2) does NOT update the current location.

In the PC-12 the GPS1 gets replaced by the GNS 750 when you activate it. But then the GPS2 (default GNS 530) does not work either.

Please let me know if the second default GPS works in your setup when you activate a RXP GTN unit. Thank you for your support.

Hi, I guess I've misinterpreted your message. Although they might run alongside, there might be some subtleties with the 2nd default GPS, especially because there is nothing in X-Plane to set default #1 or default #2 as the one 'driving' the rest of the avionics: they are somewhat 2 different views of the same single core GPS simulation.

So, just to understand it correctly. Currently there is no way to use the GTN as GPS 1 and also use the default 530 as a second GPS? I also have the PC-12 and, while the GTN works as expected, the 530 unit below it (default XP GPS) does not work.

 

There is no way to use this second GPS?

Hi, I'm not sure about this one but sure enough, X-Plane SDK only offers an all-or-nothing 'GPS override' dataref, which I supposed affects both or none only. Should it be designed like this inside X-Plane code, there is little we can do for now unfortunately.

Of course, you'll get much more out of our GNS V2 which is designed to run along any other RXP GPS (GNS V2 or GTN).
