Autopilot In‐Flight Tuning Procedures
Detailed Explanation
1. Establish trimmed level flight on a fixed heading
You should start the procedure by placing the aircraft in level flight, in neutral trim, on a fixed
heading. Try to maintain a constant altitude during the procedure.
2. Engage the Autopilot (AP) in TRK+ALT mod
To engage the autopilot in TRK+ALT mode:
1. Enter the AP Menu (MAIN MENU > AP)
2. Press button 3, TRK+ALT
3. It should be highlighted and look like
Note that the heading (HDG) bug under the DG changes to the track (TRK) bug in track mode.
3. Allow a few minutes of stable flight under AP control
Ensure that you are not affecting the autopilot's control of the roll axis, so you can determine
the autopilot's track hold and turn performance.
4. Change the TRK target 90 degrees from the current target
Change the heading bug to 90 degrees to the left or right of current heading.
1. Configure a joystick to control the heading bug. The label above the joystick should read
(TRK)
2. Turn the joystick either way until the track bug reads 90 degrees to the left or right of
current TRK target
3. The aircraft should immediately begin turning toward the new TRK target
5. Check for ROLL SLIP indications
Observe the autopilot status indicator on the Top Bar while the autopilot flies. If the
banner is shown frequently, it is an indication that the roll servo is slipping and
the servo torque needs to be increased. Occasional slips due to turbulence are acceptable.
If frequent ROLL SLIPS are observed, disconnect the autopilot and increase ROLL TORQUE by
10% (SETUP MENU > AUTOPILOT SETUP > ROLL AXIS > TORQUE).
If you have adjusted the roll servo torque to 100% and are still seeing frequent
slips, you may need to try a higher strength servo (e.g., if you have an SV32
installed, try swapping for an SV42). Contact Dynon for assistance.
6. Check if aircraft is slow to respond
Observe the speed at which the autopilot responds to changes in TRK setting.
If the autopilot seems too slow to respond or "sluggish", disconnect the autopilot and increase
ROLL SENSITIVITY by 2 (SETUP MENU > AUTOPILOT SETUP > ROLL AXIS > SENSITIVITY).
