Features - Century 2000 Pilots Operating Manual

The Century 2000 Autopilot
This autopilot only version uses a standard artificial horizon in
combination with a directional gyro (DG) or an NSD-360A, NSD-1000
Horizontal Situation Indicator (HSI). A Century Flight Systems, Inc. Yaw
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. Examples of
controlled rate motion are as follows:
ROLL AXIS:
Heading Command - Roll at 5° ° per second diminishing near bank
limit.
Navigation Soft Mode - Roll at 2.5 degrees per second to reduced
bank limit (8° ° ).
Gust Disturbances - Resisted by certificated servo velocity.
*PITCH AXIS:
Command Attitude - 0.7° ° per second attitude change.
Gust Recovery - Maximum rate consistent with passenger comfort.
Maximum System Capability - 2.4° ° per second .
