The next phase of setting up the Garmin autopilot system is to verify the proper
functionality of the yaw damper system on the ground in normal mode. This phase
of the checkout requires a valid output from the G5. This means the post installation
procedures must have been completed on the G5 before performing the on ground
autopilot normal mode checkout.
1) Leave the yaw damper disengaged and verify the rudder pedals can be
manipulated smoothly with no control system binding.
2) Engage the autopilot in YD mode.
3) Press the YD button on the GMC 30X.
4) Verify the rudder properly moves to the correct direction by standing by the
tail of the aircraft, facing the vertical stabilizer, and pushing on the fuselage.
The rudder should move AWAY from you (the rudder should move in the
same direction that the rear fuselage is moving):
a) If the rudder does not move the correct direction, correct the yaw servo
direction documented in the Servo Wiring Checkout.
5) Engage the yaw damper and verify it can be overpowered in the yaw axis
using rudder pedal inputs. If the autopilot cannot be overpowered, use the
Yaw Damper configuration page to reduce the Maximum Torque setting for
the yaw damper servo.
6) The CWS/DISCONNECT input can optionally be connected to the Yaw
Damper. If this connection was made, engage the yaw damper and verify
that it properly disconnects with a short press and release of the CWS/
DISCONNECT button.
