Servo Wiring Checkout
The first phase of setting up the Garmin autopilot system is to verify the proper wiring of the GSA 28
servos while on the ground.
1. If the installation is a 1-axis (roll only) autopilot, use the LRU page in configuration mode on the
PFD to configure the “Autopilot Servos” for “Roll Only”.
2. If you have installed a 2-axis (pitch and roll) autopilot, use the LRU page in configuration mode on
the PFD to configure the “Autopilot Servos” for “Pitch + Roll”.
3. If you have installed a 3-axis (pitch, roll, and yaw) autopilot, use the LRU page in configuration
mode on the PFD to configure the “Autopilot Servos” for “Pitch + Roll + YD”.
4. Go to the System Information page in configuration mode and verify the Roll, Pitch, and Yaw
servos are properly communicating with the system indicated by a green check box.
