Roll Servo Flight Tuning Procedure OverviewAutopilot Servo Installation, Configuration, and CalibrationThe following list is an overview of the roll servo flight tuning procedure. Each step is describedin more detail after the list.1. Verify preferred turn rate limit and bank angle limit.2. Ensure the aircraft is in trim.3. Engage the autopilot in track mode.4. Allow a few minutes of stable flight under autopilot control.5. Adjust roll servo torque and/or sensitivity values as needed.6. Change the track bug 90 degrees from the current track.7. Verify roll torque and sensitivity settings during turn(s).8. Verify turn rate limit and bank limit settings during turn(s).9. Disengage the autopilot.Verify preferred turn rate limit and bank angle limitPerform the following steps:1. Enter the Roll Axis Menu (SETUP MENU > AUTOPILOT SETUP MENU > ROLL AXIS).2. Verify the TURN RATE TARGET and MAXIMUM BANK ANGLE are set to values that arewithin your comfort limits.3. These values are configurable before, during, and after flight. Use the instructions foundin previous sections (i.e., the Maximum Bank Angle and the Turn Rate Target sections)to adjust these values.Ensure the aircraft is in trimThis test procedure tunes the autopilot’s roll axis control. It is critical to isolate this axis andthus, you should start the procedure when the aircraft is in neutral trim and maintain aconstant altitude during the following steps.Engage the autopilot in track mode1. Enter the AP Menu (MAIN MENU > AP MENU).2. Press button 2 to engage the autopilot in track mode. The button label should changefrom to and the Top Bar autopilot status indicator should change to.3. Ensure that the autopilot pitch axis is disengaged. If needed, press button 4 until itslabel looks like .Allow a few minutes of stable flight under autopilot controlNote that the autopilot is flying in track hold mode, so you will need to control the aircraft’spitch. Ensure that you are not affecting the autopilot’s control of the roll axis, so you candetermine the autopilot’s track hold and change performance.SkyView System Installation Guide - Revision J 10-23
