Hi folks,today, for the first time i encountered a problem with FMC TAKEOFF REF page: after loading all data as usually in INIT/PERF and loaded/activated my flightplan i go to TAKEOFF REF, set Flaps 5

Are you sure your pressing the Execute key on the FMC when it,s lit.Best

Oh yessir,flightplan is activated and executed. As usual.This problem appears on the 800-900 series and also, give a look at the Vref i got only a few miles of LHBP Rwy 31 :-cool Never had this trouble with 600-700 series.Surely i need help!Luigi ;-)http://forums.avsim.net/user_files/90272.jpg

Hi Randy,think you're right. Of course.And, what about those dead takeoff clicks?cheersLuigi ;-)

Thanks for helping troubleshooting. I really do not know how did i changed units...Luigi ;-)

Hi Luigi,maybe a dumb question: which units are you using for weights ?If inadvertently you are messing up with kgs and lbs, maybe this could be the cuplrit in the high Vref...Check the units, sometimes (I don't know why, but it happened to me at least once, I normally using Kgs, but it went to Lbs), FS seems to change your settings...Hope this hepls
