FLIGHT MANAGEMENT

APPROACHES

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 "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 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 G1000 SBAS GPS allows for flying LNAV, LNAV+V, LNAV/VNAV, LP, LP+V and LPV approach service
levels according to the published chart. The '+V' designation adds advisory vertical guidance 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. The active approach
service level is annunciated on the HSI as shown in the following table
