Typically, you do not have several different GPSs in the same airplane..
 
So you would replace the built in GPS by the GTN 750.
 
The GTN will drive an FS autopilot, just the same way the built in GPS would.
 

 

True point.  But since this airplane does not appear (to the best of my research) to let you build the GPS into the airplane, how does it work? Ditto for several other Carenado aircraft (the SR-22).

Well it is awkward at best..

 

In case of the PC12, you can kind of shoehorn it into the place of the upper GNS.. does not look great, but it works.

 

SR22.. no idea..

 

You start looking for planes that are designed for the GTN... a2a Comanche, Carenado F406 Caravan II, RealAir Duke Turbine V2 etc.

 

That is the real way to go IMHO..

Hmmm...Interesting stuff.  So while it does not look good, the autopilot and NAV displays (CDI) will follow the GPS course though?

Yup  :smile:

The GTN has a switch to select whether the AP nav source is the GTN or the default GPS, you right click the blue SD card to change it and the tooltip tells you which is in use. By default when a GTN-equipped plane loads nav source will be set to use the GTN.

Thanks guys for the hopes!
