Autopilot Servo Installation, Configuration, and Calibration
10-14 SkyView System Installation Guide - Revision K
To test roll axis servo override:
1. Return to the Main Menu.
2. Center the aircraft controls.
3. Enter the Autopilot Menu (MAIN MENU > AP).
4. Press HDG:OFF. Note that the mode toggles to HDG:ON and the roll servo engages.
Now, take the controls and override the servo by moving to either roll left or roll right
(remember, you are only overriding the roll servo, so you should feel no resistance in the pitch
axis). Ensure that you are comfortable with the amount of force it takes to override the servo. If
you are not, decrease the roll servo torque value by 10% and repeat the test. Do note that air
loads may decrease the amount of effort required to override the servo.
Roll Axis Sensitivity
The roll axis sensitivity parameter specifies the how fast or slow the AP responds to deviations
between commanded direction and actual heading or track. If sensitivity is set too low, the
aircraft will wallow during changes in heading. If sensitivity is set too high, the aircraft will be
twitchy, with frequent, fast, aggressive adjustments. Sensitivity is specified in digits. The
minimum is 1 and the maximum is 24 (low to high sensitivity, respectively). The default value is
10.
This parameter can be tuned in flight in the Roll Axis Setup Menu (IN FLIGHT SETUP MENU >
AUTOPILOT SETUP > ROLL AXIS > SENSITIVITY). Leaving it at the default of 10 is sufficient for
initial setup. If the autopilot is not as decisive as you would like, increase this value. If it is too
aggressive, decrease it.
To adjust the roll axis sensitivity value:
1. Go to the Roll Axis Sensitivity Adjust Page (SETUP MENU > AUTOPILOT SETUP > ROLL
AXIS > SENSITIVITY).
2. Adjust the sensitivity number.
3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.
Roll Axis Mode
You can set the roll axis mode to either bank angle or turn rate. If the roll axis is set to the bank
angle mode, the autopilot will more directly control the bank angle of the aircraft instead of
targeting a specific turn rate during autopilot-commanded turns. The maximum bank angle that
the autopilot allows is set by the bank angle target parameter.
If the roll axis is set to turn rate mode, the autopilot will more directly control the average turn
rate of the aircraft during autopilot-commanded turns while still obeying the maximum bank
angle. The maximum turn rate and bank angle that the autopilot allows are set by adjusting the
turn rate target and maximum bank angle parameters.
To choose the roll axis mode:
1. Go to the Roll Axis Mode Page (SETUP MENU > AUTOPILOT SETUP > ROLL AXIS > MODE).
2. Choose the mode.
3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.
