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 only 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 approa
ch the SkyView’s HSI source must be
switched from
GPS to NAV. This may happen one of two ways:
(1)
If the GPS does not support auto-switching from GPS to NAV, you must manually
perform this action by using AUTOPILOT > HSI SRC.
(2)
Some devices, such as the Garmin 430, 430W and GTN series, can automatically
change from the GPS to the localizer and send a signal to the SkyView to
automatically change the HSI source at the appropriate time. If your external
GPS/NAV device is configured with this behavior enabled, one important detail is
that such devices ALWAYS control whether its GPS or NAV radio is providing
guidance. Therefore, when configured for auto-switching, you must use that
device’s CDI or NAV/GPS toggle to change whether it’s NAV or GPS guidance is
shown o
n SkyView’s HSI. SkyView’s own HSI SRC button can only see EITHER the
GPS or NAV side of the device at any time.
Missed Approach (Go around)
The Go Around (GA) function of the autopilot allows the pilot to quickly manage the
transition from a descending precision approach to a climbing missed approach. The
function is available when the autopilot is active in VNAV mode (such as following the glide
slope) and replaces the NOSE UP button once captured. Upon activation of the GA function
the active vertical autopilot mode switches to VS with the default climb vertical speed target
or IAS with the current indicated airspeed target. The lateral autopilot mode switches to TRK
with the current track. ALT hold mode at the altitude bug is always armed. The active vertical
mode is determined by Autopilot Setup.
This go around feature is solely intended to initiate the missed approach
–
specifically the transition in vertical navigation. It does not follow the published go
around procedure. SkyView is not a substitute for an IFR navigator, has no
