If certain GPS parameters (SBAS, RAIM, etc.) are not available, some published approach procedures
note:
for the desired airport may not be displayed in the list of available approaches.
An Approach Procedure (APPR) can be loaded at any airport that has one available, and provides guidance
for non-precision and precision approaches to airports with published instrument approach procedures.
Only one approach can be loaded at a time in a flight plan. If an approach is loaded when another approach
is already in the active flight plan, the new approach replaces the previous approach. The route is defined by
selection of an approach and the transition waypoints.
Whenever an approach is selected, the choice to either "Load" or "Load & Activate" is given. "Loading" adds
the approach to the end of the flight plan without immediately using it for navigation guidance. This allows
continued navigation via the intermediate waypoints in the original flight plan, but keeps the procedure
available for quick activation when needed. "Activating" also adds the procedure to the end of the flight plan
but immediately begins to provide guidance to the first waypoint in the approach.
When selecting an approach, a "GPS" designation to the right of the procedure name indicates the procedure
can be flown using the GPS receiver. Some procedures do not have this designation, meaning the GPS
receiver can be used for supplemental navigation guidance only. If the GPS receiver cannot be used for
primary guidance, the appropriate navigation receiver must be used for the selected approach (e.g., VOR or
ILS). The final course segment of ILS approaches, for example, must be flown by tuning the NAV receiver to
the proper frequency and selecting that NAV receiver on the CDI.
The SBAS GPS allows for flying LNAV, LNAV/VNAV, LP, and LPV approaches according to the published
chart. LNAV+V is a standard LNAV approach with advisory vertical guidance provided for assistance in
maintaining a constant vertical glidepath similar to an ILS glideslope on approach. This guidance is displayed
on the system PFD in the same location as the ILS glideslope using a magenta diamond. In all cases where
LNAV+V is indicated by the system during an approach, LNAV minima are used. The active approach type
is annunciated on the HSI as shown in the following table:
HSI Annunciation
LNAV GPS approach using published LNAV
minima
LNAV+V GPS approach using published LNAV
minima. Advisory vertical guidance is
provided
L/VNAV GPS approach using published LNAV/
(available only if VNAV minima (downgrades to LNAV if
SBAS available) SBAS unavailable)
LP GPS approach using published LP
(available only if minima (downgrades to LNAV if SBAS
SBAS available) unavailable)
LPV GPS approach using published LPV
(available only if minima (downgrades to LNAV if SBAS
SBAS available) unavailable)
