Hello,
It's been a couple of days and I tried reinstalling the software (RXP and PC 12)and read protecting the file, didn't work. I check the .ini file before I load the aircraft and it shows Masterdevice =true after attempting to follow a GPS flight in the PC 12 the aircraft does not follow the course on Autopilot with GPS selected. That's when I know it's not working I check the settings in game and the Masterdevice is unchecked, then I check the .ini file, it shows "false".
You mentioned aircraft loading and changing settings possibly or some other plug ins or scripts causing the problem. I'll look for the RXP log if it has one as well. Is there anything like scripts or how the aircraft reloads that I could investigate. I can look at .xml or any other code, just need an idea where to start if you have any. I don't think other PC 12 owners are having this problem, has to be my system, Windows 10, 64bit, 32 GB ram, 1080 Ti.
Thanks for any help or ideas
