Hello crewmembers!Sometimes, i have the following problem with the FMC during cruise:It cannot make up her mind about where the T/D point is going to be. It changes back and fwd every second. Sometimes this also happens with the speed, resulting that my thrust is bouncing up and down like crazy!Anyone an idea how i can stop this?Cheers,Ian Udingahttp://www.precisionmanuals.com/images/forum/800driver.jpg

I have zero wind and clear skies!Cheers,Ian Udingahttp://www.precisionmanuals.com/images/forum/800driver.jpg

You need to give details so we don't play guess the issue ;-) What if anything are you running? 0 winds doe that mean that you do NOT have any weather program running? Have you tried re-installing? DOes it only happen on that one aircraft? And any other things that you think can help us help you.[h4]Best Wishes,Randy J.
