hello. my pmdg problem is about the activate autopilot. after all done with FMC setting. and running.. TOGA mode. rotate.. gear up.. after 1000ft, I pushed cmd a button. but it dissarmed soon.. and AP First alarm appears aboce ND.. so I tried again with push LNAV button before takeoff. (VNAV didn't pushed) after rotate.. same problem happen.. I really want to know what is the problem is.. autopilot disarmed. so I had to follow FD manually.. H~E~L~P here's my video capture.. http://www.startinmylife.com/pmdg.wmv

I didn't see anything wrong on your video capture. My only thought would be trim. Are you manually adjusting trim after autopilot activation?

Hi there,Watched the video.When you hit CMD a window in transparency display above right of the screen.Can't see what it is... Could this be part of the problem ?anthony

I didn't use any trim.. and I didn't touch anything without gearup after takeoff..

screen of above right? that's ATC window..
