    NOTE The Century 2000 Autopilot is a modular design. It may be installed and operated as a roll axis only autopilot, roll and pitch axis, or a roll, pitch, and yaw axis. The asterisk symbol (*) appearing before certain sections of this manual indicates instructions for those systems having the pitch expansion installed.

    Damper (Y/D) may be incorporated with the Century 2000 when a Y/D is certified for your plane. An outstanding feature of the Century 2000 is that it has a rate based inner loop for short term dynamics. This means that rate information is derived from the horizon so that motion about the roll and pitch axis is programmed to occur at a rate appropriate to the activity.
