How is this accomplished?

When you engage the AP pitch channel (the right switch), your joystick should be centered and the aircraft should be trimmed to mantain the climb. As soon as the AP engages the aircraft will be in Control Wheel Steering mode (CWS) and from this moment on, you can adjust the pitch with your joystick (or yoke) and the AP will mantain it.Cheers,Daniel

ok, thanks...i'll give it a try! trim however is very sensitive :S

I had also a very sensitive trim, but it turned out to be a typo in the aircraft.cfg of the FFX model. Read the readme included in patch3 and you'll see how to correct it. The TM2 model should be ok in this regard.

i don't have any FFX models (too my knowledge, unless they are included), but it is far too sensitive in the TM2 ones as well. and thanks, the pitch idea helped!!
