Autopilot Operation
8-28 SkyView HDX Pilot’s User Guide – Revision B
Change Altitude with Vertical Speed
1. Adjust the altitude bug to the new desired altitude.
2. If you weren’t already climbing or descending, initiate the climb or descent with the
NOSE UP / DN buttons or adjust the vertical speed bug.
3. This automatically engages VS->ALT mode.
Change Altitude with Indicated Airspeed
1. Adjust the altitude bug to the new desired altitude.
2. Press the IAS button.
3. If you weren’t already climbing or descending, initiate a climb or descent with the NOSE
UP / DN buttons to adjust the autopilot’s target airspeed. Or adjust the airspeed bug or
adjust the aircraft’s power.
Track a Navigation Source
1. This procedure is identical whether you are tracking an enroute navigation source (GPS
or VOR) or a non-precision approach (GPS, VOR or LOC).
2. Select a navigation source on the HSI (MENU > AUTOPILOT > HSI SRC).
3. The navigation source must be providing valid course and deviation information.
4. Press the NAV button.
5. If the CDI is already near-centered NAV mode will immediately become active.
Otherwise NAV mode will arm.
6. If NAV mode is armed, adjust the current mode’s target (heading, track or roll) to
establish the desired intercept with the navigation source.
7. NAV mode will become active once the navigation source CDI can be captured by the
autopilot.
Precision Approach
1. Select a navigation source on the on the HSI (MENU > AUTOPILOT > HSI SRC).
a. The external navigation source must be providing valid course and deviation
information.
2. When cleared for the approach, and in ALT Hold mode:
a. Press the NAV button in the Roll Menu.
b. Press the VNAV button in the Pitch Menu.
3. Adjust the current modes target (heading, track or roll) to establish the desired
intercept with the navigation source or follow ATC vectors.
4. NAV mode and VNAV will sequence independently once their CDI / GS indications can
be captured by the autopilot.
a. Note: If a precision GPS approach is being flown with an approach approved
GPS navigator and the autopilot is already in NAV mode (i.e. not flying vectors
to final) arming of NAV mode is not necessary. Only VNAV will need to be
armed when cleared for the approach.
b. Note: If an ILS approach is being flown with another navigation source being
used in the transition, for example an approach approved GPS navigator, upon
being cleared for and activating the approach the SkyView HDX’s HSI source
must be switched from GPS to NAV. This may happen one of two ways:
