Autopilot Operation
8-14 SkyView HDX Pilot’s User Guide – Revision B
Altitude hold mode keeps the aircraft flying at a
particular altitude. The altitude that the autopilot
holds is governed by the ALT (altitude) bug. When the
autopilot is initially engaged, the ALT bug will
automatically be synchronized to your current
altitude. Effectively, this means that the autopilot will
maintain the altitude that the aircraft was at the
moment before the autopilot was engaged. After the
autopilot is engaged, you may adjust the altitude that
the autopilot holds by adjusting the ALT bug.

Moving the ALT (altitude) bug away from the current
altitude (when already holding altitude) automatically
initiates a climb or descent to the new altitude in
vertical speed mode.
The rate of climb or descent during autopilot
controlled changes in altitude is governed by the VS
(vertical speed) bug. When the autopilot is engaged
and a new altitude is selected, the Autopilot will
automatically choose one of two preset default
vertical speeds to perform that altitude change,
depending on whether or not the Autopilot needs to
climb or descend. These default climb and descent
vertical speeds are configured during Autopilot setup.
See the SkyView Classic / SE / HDX System Installation
Guide for further details on adjusting these defaults.
Once the Autopilot is climbing or descending to a new
altitude, the VS bug can be adjusted by you at any
time.
