I am trying to run the 767 style Efis and gaige set-up and am having this issue.
It keeps reverting back to 737NG stly PFD only after it's on for about 1-3mins. I set the type in the PFD.ini to 767 and force efis=on re-set everything and it works fine for 1-3mins then changes all on it's own for no reason.
How do i get it to stay on the 767 style display???
Thanks
