Whenever an approach is selected, the choice to either ―load‖ or ―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 on the Active Flight Plan Page
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 ap-
proach.
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 naviga-
tion guidance only.
If the GPS receiver cannot be used for primary guidance, the appropri-
ate 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 G1000 SBAS GPS allows for flying LNAV, LP, LP+V and LPV approach service
levels according to the published chart. The ‗+V‘ designation adds advisory vertical guid-
ance 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 loca-
tion as the ILS glideslope using a magenta diamond. A sample of how the active ap-
proach service level is annunciated on the HSI is shown in the following table:
