PROCEDURES
Not all approaches in the database are approved for
GPS use. As you select an approach, a 'GPS' designation
to the right of the procedure name indicates the procedure
can be flown using the GPS receiver. Some procedures
will 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,
you must use the appropriate receiver 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.
A selected approach can be activated or loaded.
Activating the approach also initiates automatic CDI
scaling transition as the approach progresses. In many
cases, it can be easiest to "Load" the full approach while
still some distance away, enroute to the destination airport.
Later, if vectored to final, use the following steps to select
'Activate Vector-To-Final' – which makes the inbound
course to the FAF waypoint active. Otherwise, activate
the full approach using the 'Activate Approach?' option.

To activate an approach procedure:

plan, press the PROC key to display the Proce-
dures Page.
2. Turn the large FMS knob to highlight 'Activate
Approach'.
Press the ENT key.

CAUTION: The G1000 is designed to only
complement printed approach plates and vastly
improve situational awareness throughout the
approach. The approach must be flown as it
appears on the approach chart.

NOTE: The GPS approach examples given in
the next section are not to be used for naviga-
tion. They are to be used in conjunction with
the G1000 PC training simulator software for
practice in learning what types of approaches
the G1000 supports.
