Autopilot and Trim
Mungo:
I confess to not being a professional pilot, and my few experences in icing, many years ago, taught me to stay far away or go commercial. But my B36TC Bonanza maintains altitude on A/P by continuously adjusting elevator trim. So in general, turning off the autopilot hands me an airplane with perfect elevator trim for its configuration, although I am always holding on tight just in case.
Are you saying that on the Dash 8 the autopilot holds attitude/altitude by brute force and does not adjust trim?
Just curious.
