I have this problem with the 737 and now with the 747. I tried the loadmanager but that didn't help. I checked all earlier posts but nothing helps.Here is my aircraft.cfg.. I'm going crazy, just bought this one and now this one is also giving me problems.

here's 2 of many things that can cause this.1)Are you using FSPassengers? If you are, I had the same problem with the demo version, but I don't know what the fix is.2) You are overweight and runnung full tanks with an overload on ZFW.Hope it helps a little.Dan

Dan, thnx for your reply....I don't use FSPassengers.I don't think I'm overweight, all numbers are black in LoadManager...

well hopefully someone else can chime in and solve it. Those are the two things that caused that problem for me.Good Luck

Had this problem myself with the 737. If I ignored the message, it would disappear during climb-out and not come back on that perticular flight. Had to uninstall/reinstall in the end I think - or maybe I deleted the FS9.cfg file - can't remember but the later is worth a try.

Hi !I've had this problem as well, and it looks like some software I installed changed the locale configuration of the number grouping and decimal symbol (they were switched). Once I reverted to decimal symbol being dot (.) and number groupping being comma (,), everything went back to normal.You can try this to see if this solves your problem.Serban
