This issue is driving me crazy, the worst part is that it seems to be intermittent. I have had a long break from the sim, but on coming back and clearing out the cobwebs I ran into this issue. It happens getting ready for departure, when first setting up the Perf/Takeoff data, and once it occurred I could not find a way to "fix" it. I decided maybe something had gotten corrupted so I uninstalled/reinstalled the latest version just to be sure. The weird thing is I completed a flight last night successfully but today its occurring again.
One bit of data, I noticed that when this issue occurs the temp display on the PFD is showing "--", have no idea if its related or not. Yes, I've read whatever reports on this that I could find, and have tried all the various suggestions out there, fiddling around with the second FMS, mucking with the QNH, etc etc.. Nothing seems to help. Right now I am not confident that I have a known good/known bad setup.
I saw a bug/item in the 1.7 changelog listing this as a fix, but clearly something is still wrong. I'd really like to do some flights for Onair with this plane, please help!
Cheers,
Jack
