I did a search on the forums and came up with nothing on this so my apologies if it has already been asked. My problem comes during climb and descent. The autopilot seems to be extremely erratic during these phases. The aircraft always seems to pitch up very far bringing my VS to around 6,500. It isn't as bad on descent but it still wants to act very quirky. The only thing I can think of is that it may have something to do with the trim. No clue what though. Thanks for any help.

Hello Nick,I suggest checking the PMDG forum for this one.Usually issues like this can be cleared by doing a clean re-install of the PMDG 737. Cheers,Bryan

Sounds good I'll check over there. I posted here because this only became an issue after I started using Fs2Crew. I'll see what I can find though.Thanks Bryan.
