ADDITIONAL GUIDANCE FOR RNAV GPS
Ed. 1, Rev.0
Whenever an approach is selected, the choice to either ―load‖ or ―activate‖ is giv-
en. ―Loading‖ adds the approach to the end of the flight plan without immediately
using it for navigation guidance. This allows continued navigation via the inter-
mediate 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 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 proce-
dures 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 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 adviso-
ry vertical guidance for assistance in maintaining a constant vertical glidepath
similar to an ILS glideslope on approach. This guidance is displayed on the sys-
tem PFD in the same location as the ILS glideslope using a magenta diamond. A
sample of how the active approach service level is annunciated on the HSI is
shown in the following table:
