SkyView Autopilot In-Flight Tuning Guide - Revision B 1-1
1. Overview
Purpose
The goal of the AP tuning procedure is to maximize the performance of the Autopilot in your
aircraft. The steps described accomplish this systematically and reduce guesswork, so follow
them carefully.
All procedures in this guide should be exercised regardless of how the autopilot is intended to
be used in the aircraft. In particular, if you are using the vertical navigation features of the
autopilot, pay special attention to the IAS Hold tuning procedure. Tuning this well will give the
best results when using vertical guidance.
Once IAS hold is well tuned, the AP will be able to get the best performance during normal
climbs and descents in either expert or simplified modes, and the altitude capture and hold
procedure should be used to finalize vertical performance.
Once you have configured the autopilot to capture and hold airspeeds and altitudes, you may
wish to adjust the ride quality in turbulence, particularly on the glideslope.
Similarly, the Roll Axis TRK and Turns Procedure will ensure best performance both in normal
turns and when following lateral guidance on approaches.
It is critical that once tuned, you familiarize yourself with AP procedures, and verify
the performance of the autopilot on approaches in VMC before use in IMC.
Performance of the AP is degraded by excessive servo slippage. If during
verification of approach performance you find that the servo is slipping, verify that
you have the torque set to the maximum value, and if slips continue, contact Dynon
for advice on servo sizing.
HDG mode performance is only as good as your compass calibration. If you have
concerns about your compass, refer to the compass calibration guide in the
SkyView System Installation Guide.
The SV-AP-PANEL is enabled when AP CONTROLS are set to EXPERT mode. For
tuning procedures performed in SIMPLIFIED mode, the buttons on the SV-AP-PANEL
will not be active.
