Using dual GNS 530 with external controllers
-
I use the Octavi IFR-1 to control my avionics and auto pilot. There is a toggle function to control "FMS1" and "FMS2". In other addons with GNS 530 + 430 units, say the analog 172 and other BkSq addons, I can separately control the units by choosing "FMS1" or "FMS2".
However, in the TBM 850 with dual GNS 530 units, FMS1 controls both 530 units. So, I end up using the older analog radio stack as my secondary radio option. It would be really nice to be able to use the second 530 for displaying the flight plan or TCAS instead though.
Are there separate variables to control the first and second GNS 530 units?

Indeed there are! I actually asked Working Title if my method was the best way to accomplish this, and they now recommend it in their documents to other developers. I don't know what the Octavi IFR-1 is doing, but you can control each unit independently by adding the correct index to the HTML event. For example, the Direct-To buttons for the GNS 530 would be...
AS530_1_DRCT_Push AS530_2_DRCT_PushLet me know if if you need any more help with these events. Every hardware setup can be a little different, but I have many happy home cockpit builders who are using both units with their hardware.

Thanks for the reply - I suspect the "FMS2" functions are not being mapped to the AS530_2_... commands given few if any aircraft in the sim have a GNS530 as the secondary GPS unit. I will reach out to the Octavi folks.
