Perhaps one of the real-life pilots can verify this story.http://ftp.avsim.com/dcforum/DCForumID8/3291.html

Sounds too comical to be true. But who knows ?Pictures however I believe to be real ;-)On the subject of green '--F' (didn't you have this problem ?) - I now know how to get it back if it disappears - don't have to reload any scenarios.Michael J.

Yes sir, that was me. "My little green Fs up and flew away." I got them back though. I reloaded a default PIC flight with a default PIC aircraft and back they came. Then I switched to my preferred 767 aircraft and save the flight. Been OK ever since. What method did you discover to get them back? And what in the world caused them to disappear? I never did figure that out.

Once soon after takeoff I noticed the green -F was gone.But then my FMC was in a state that was showing preflight COMPLETE - nothing beyond that. What I did I simply hit INDEX and opened both the TAKEOFF and APPROACH pages. As soon as I did that (not sure which page did it) the green -F was back. :-hmmmMichael J.
