Roll Trim Indicators
When the autopilot is flying the aircraft in the roll axis, a Roll Trim Indicator may appear. This
indicator lets you know when the roll servo is having to maintain a sustained force on the
ailerons in order to hold the desired bank angle. To eliminate the excessive trim forces that the
autopilot is trying to overcome, trim aircraft in the direction indicated: left or right. Adjust the
trim in small increments and wait a few seconds between adjustments to see whether the
adjustment is sufficient to remove the out-of-trim indication. This alert may not be configured
in all aircraft. See the SkyView System Installation Guide for more information regarding trim
indication configuration. If you have roll Auto-Trim configured on the roll axis, the autopilot will
automatically apply trim commands to resolve the out-of-trim condition and the Autopilot
engaged arrows will turn to the left or right.

Roll Slip Indicator
You may see this during periods of turbulence or if the strength of the servo is not sufficient to
actuate the control surface. If slipping occurs on the roll servo, SkyView displays a slip warning
as illustrated in the following figure. Reference the SkyView System Installation Guide for more
information regarding servo slippage.
