3.1.5 ROLL AXIS

The autopilot roll axis uses roll rate to stabilize aircraft roll attitude during flight

director maneuvers. The flight director roll commands are rate- and attitude-limited,

combined with roll damper control, and sent to the roll servo motor.

The yaw damper uses yaw rate and roll attitude to dampen the aircraft's natural

Dutch roll response. It also uses lateral acceleration to coordinate turns and reduce

or eliminate the need for the pilot to use rudder pedal force to maintain coordinated

flight during climbs and descents.

Control Wheel Steering allows the aircraft to be hand-flown without disengaging the

AFCS. Press and hold the autopilot CWS Button (if equipped) to temporarily disengage

the pitch and roll servos from the flight control surfaces and hand-fly the aircraft.

The G5 autopilot control is synchronized to the aircraft attitude during Control Wheel

Steering. The green 'AP' annunciation is temporarily replaced by a white 'CW' for the

duration of Control Wheel Steering maneuvers.

The AP Disconnect and CWS are, in most configurations, the same button, where

the AP Disconnect can be configured to also provide CWS functionality. The pilot

can interrupt ESP by pressing and holding the Autopilot Disconnect / Control Wheel

Steering (AP DISC/CWS) switch. Upon releasing the AP DISC/CWS switch, ESP force

will again be applied. ESP can also be overridden by overpowering the servo's torque

limit.

In most scenarios, releasing the CWS Button reengages the autopilot with a new

reference, when configured. Refer to (Vertical Modes) and (Lateral Modes) for Control

Wheel Steering behavior in each mode.
