I'm testing my installation, Murphy Moose with capstain drive servo's. When the AP is disconnected I go a pitch down. The procedure used is trim airplane with AP off and then engage AP for straight and level. The AP slips and calls for trim and I trim until no slip and trim request. When the AP is disconnected pitch down is a 2000+fpm decent. Why is AP calling for trim when airplane was in trim to begin with?
