Servo Wiring Checkout
The first phase of setting up the 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 Flight Controls
configuration page to configure the autopilot servos for roll only.
2) If the installation is a 2-axis (pitch and roll) autopilot, use the Flight
Controls configuration page to configure the autopilot servos for pitch and
roll.
3) If the installation is a 3-axis (pitch, roll, and yaw) autopilot, use the Flight
Controls configuration page to configure the autopilot servos for pitch and
roll and enable the yaw damper.
4) Ensure the pitch, roll, and yaw servos are properly communicating by
checking the Device Information configuration page. Each device should
have a green check mark next to it.
5) Select the Autopilot Roll Servo configuration page and verify the proper trim
activity with the servo connected to an auxiliary trim motor.
a) Center the aileron trim switch to input no trim command. Verify the
aileron trim switch is not moving. Verify the roll servo is properly
indicating no trim activity.
b) Use the aileron trim switch to input a roll right trim command. Verify
the aileron trim switch properly moves for roll right trim. Verify the roll
servo is properly indicating roll right trim activity.
c) Use the aileron trim switch to input a roll left trim command. Verify the
aileron trim switch properly moves for roll left trim. Verify the roll servo
is properly indicating roll left trim activity.
d) If the aileron trim response is reversed, select Reverse for the Trim
Motor Direction, then repeat all of step 5.
6) Select the Autopilot Pitch Servo configuration page and verify the proper
trim activity with the servo connected to an auxiliary trim motor.
a) Center the elevator trim switch to input no trim command. Verify the
elevator trim switch is not moving. Verify the pitch servo is properly
indicating no trim activity.
