Engagement; Control Wheel Steering - Garmin Socata TBM850 Pilot's Manual

ENGAGEMENT

Autopilot engagement/disengagement is not equivalent to servo engagement/disengagement. Use
NOTE:
the CWS Button to disengage the pitch and roll servos while the autopilot remains active.
When the AP Key is pressed, the autopilot, yaw damper, and flight director (if not already active) are activated
and the annunciator lights on the AFCS controller for the autopilot and yaw damper are illuminated. The flight
director engages in Pitch and Roll Hold Modes when initially activated.
When the YD Key is pressed, the system engages the yaw damper independently of the autopilot and the yaw
damper annunciator light is illuminated.
Autopilot and yaw damper status are displayed in the center of the AFCS Status Box. Engagement is indicated
by green 'AP' and 'YD' annunciations, respectively.

CONTROL WHEEL STEERING

During autopilot operation, the aircraft may be hand-flown without disengaging the autopilot. Pressing and
holding the CWS Button disengages the pitch and roll servos from the flight control surfaces and allows the
aircraft to be hand-flown. At the same time, the flight director is synchronized to the aircraft attitude during
the maneuver. CWS activity has no effect on yaw damper engagement.
The 'AP' annunciation is temporarily replaced by 'CWS' in white for the duration of CWS maneuvers.
In most scenarios, releasing the CWS Button reengages the autopilot with a new reference. Refer to flight
director mode descriptions for specific CWS behavior in each mode.
