Autopilot Servo Installation, Configuration, and Calibration
10-16 SkyView System Installation Guide - Revision K
Torque must be set high enough to prevent any slip due to air loads, but low enough that the
pilot can override the autopilot should the need arise. If the servo slips continuously, the
autopilot cannot fly the aircraft. Torque is specified in percent (%) of maximum the servo is
capable of exerting. The minimum is 10%, the maximum is 100%, and the default value is 100%.
To adjust the pitch axis torque value:
1. Go to the Pitch Axis Torque Adjust Page (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS
> TORQUE).
2. Adjust the torque %.
3. Press ACCEPT to save the value or press CANCEL to return to the Pitch Axis Menu.
It may take some experimentation to find the right value for your aircraft, but if you are
comfortable overriding the servo at 100% torque, it is safe to leave that setting at its default
value. Do note that air loads may decrease the amount of effort required to override the servo.
To test pitch axis servo override:
1. Return to the Main Menu.
2. Center the aircraft controls.
3. Enter the Autopilot Menu (MAIN MENU > AP).
4. Press ALT:OFF. Note that the mode toggles to ALT:ON and the pitch servo engages.
Now, take the controls and override the servo by moving to either pitch down or pitch up
(remember, you are only overriding the pitch servo, so you should feel no resistance in the roll
axis). Ensure that you are comfortable with the amount of force it takes to override the servo. If
you are not, decrease the pitch servo torque value by 10% and repeat the test.
Pitch Axis Sensitivity
The pitch axis sensitivity parameter specifies the how fast or slow the autopilot responds to
deviations between commanded altitude and actual altitude. If sensitivity is set too low, the
aircraft will wallow during changes in altitude. 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 Pitch Axis Setup Menu (IN FLIGHT SETUP MENU >
AUTOPILOT SETUP > PITCH 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 pitch axis sensitivity value:
1. Go to the Pitch Axis Sensitivity Adjust Page (SETUP MENU > AUTOPILOT SETUP > PITCH
AXIS > SENSITIVITY).
2. Adjust the sensitivity number.
3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.
