Centurion Altitude Hold

Featured Replies

How much slop is normal for the Centurion's altitude hold. I adjusted the pitch control to 0 at 12,000 feet and it slowly (2-3 feet/min) continued a descent to around 11,936ft. It then began a very slow climb back up towards 12,000. Is this normal? This is my first time using this specific autopilot and want to be sure I understand what "normal" is. I'm a bit nervous to walk away during a flight as I'm not sure if it is going to continue an unwanted, slow climb or descent.Thanks!StaceyFS9 + SPWinXP + SP3

Pretty much. The Nav-O-Matic is not the most precise AP. And I've heard stories that the actual units operate very similar to what you are experiencing.
