G3X Touch Afcs Installations Options; Control Wheel Steering (Cws) (Optional) - Garmin G3X Touch Pilot's Manual

G3X TOUCH AFCS INSTALLATIONS OPTIONS

The G3X Touch offers multiple Automatic Flight Control System installation options.
The following options are discussed in this section:
• GDU 4XX Primary Flight Display (PFD), plus a third party autopilot unit. Selecting
a FD mode engages the autopilot.
• GDU 4XX Primary Flight Display (PFD), plus GSA 28 servos. This option includes a
separate FD.
• GDU 4XX Primary Flight Display (PFD), plus third party autopilot, plus GMC
305/307/507 Mode Controller. This option includes a separate FD. The FD can
be on independent of the autopilot. Selecting a FD mode does not engage the
autopilot. This option does not support a Yaw Damper (YD).
• GDU 4XX Primary Flight Display (PFD), plus GSA 28 servos, plus GMC 305/307/507
Mode Controller. This option includes a separate FD. The FD can be on independent
of the autopilot. Selecting a FD mode does not engage the autopilot. This option
supports a Yaw Damper (YD).

CONTROL WHEEL STEERING (CWS) (OPTIONAL)

NOTE: Not all third party autopilot units support Control Wheel Steering
(CWS).
Control Wheel Steering allows the aircraft to be hand-flown without disengaging
the AFCS. Press and hold the autopilot unit's CWS Button (if equipped) to temporarily
disengage the pitch and roll servos from the flight control surfaces and hand-fly the
aircraft. The G3X Touch AFCS 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.
In most scenarios, releasing the CWS Button reengages the Autopilot with a new
reference. Refer to (Vertical Modes) and (Lateral Modes) for Control Wheel Steering
behavior in each mode.
