Recently added PMDG MD-11 to my FSX experience and like the plane very much.....Taking awhile to get used to it....I fly in VC mode mostly and notice that plane shakes (pitches and rolls) alot while in flight. I am guessing that this is the design to simulate the real flight experience... It does, however, make changing altitudes or speeds manually quite difficult.....Usually have to pause FS to accomplish the task...Is this normal display activity for this great plane or am I missing something???:Thinking:I also notice some FSX CTD errors while in flight.. Usually happens when opening other view windows...I am trying some of your CTD fixes....I have win 7 64 bit and 4 gig ram...

Look in the 'Introduction" - page 44/45. You may also want to disable turbulence effects on aircraft from within FSX options.

Thanks, I have read the whole manual and never made the connection... I'll give it a try.....
