Autopilot Operation
SkyView HDX Pilot’s User Guide – Revision B 8-15
Control Wheel Steering
When the autopilot is engaged, press and hold the Autopilot disconnect switch to put the
autopilot into Control Wheel Steering mode.
Figure 223 – Control Wheel Steering Active
While Control Wheel Steering mode is active, the Autopilot servos are temporarily disengaged.
This lets you fly the aircraft by hand for short periods to make an adjustment to the autopilot’s
targets without completely disengaging the Autopilot.
When the disconnect switch is released, the Autopilot’s targets are adjusted as follows:
When in TRK+ALT mode:
o Pitch axis: The ALT bug (and thus the Autopilot’s altitude target) is synchronized
to the aircraft’s current altitude.
o Roll axis: The TRK bug (and thus the Autopilot’s track target) is synchronized to
the aircraft’s current GPS ground track.
When in HSI+ALT mode:
o Pitch axis: The ALT bug (and thus the Autopilot’s altitude target) is synchronized
to the aircraft’s current altitude.
o Roll axis: No change. The roll axis resumes tracking its HSI source.
The Control Wheel Steering feature can be enabled and disabled via the Autopilot Setup Menu.
See the SkyView Classic / SE / HDX System Installation Guide for details.
Hold To Engage
When the autopilot is not already engaged, press and hold the Autopilot disconnect switch will
place the autopilot into Hold To Engage mode. The Top Bar annunciates REL TO ENG (release to
engage) while the disconnect switch is held.
Figure 224 – Hold to Engage Indicator
When the disconnect switch is released, the Autopilot engages in TRK+ALT mode, and the TRK
and ALT targets are both synchronized to the aircraft’s current GPS ground track and altitude.
Effectively, this operation is the same as pressing the TRK+ALT button in the Autopilot menu.
The Hold To Engage feature can be enabled and disabled via the Autopilot Setup Menu. See the
SkyView Classic / SE / HDX System Installation Guide for details.
