5) Turn the large
right
knob to highlight ‘Load?’
or ‘Activate?’ (approaches only) and press the
ENT
Key. ‘Load?’ adds the procedure to the
flight plan without immediately using it for
navigation guidance. This allows the pilot to
continue navigating the original flight plan, but
keeps the procedure available on the Active
Flight Plan Page for quick activation when
needed.
6) For precision approaches and some non-
precision approaches, a reminder window
appears indicating that GPS guidance on
such approaches is strictly for monitoring only.
Use an external VOR/ILS receiver and CDI (or
HSI) for primary navigation. To confirm this
reminder, highlight ‘Yes?’ and press the
ENT
Key.
Not all approaches in the database are approved for
GPS use. When selecting an approach, a ‘GPS’
designation
to the right of the procedure name (Figure 6-4) indicates
the procedure can be flown using the GPS receiver. Some
procedures do not have this designation, meaning the
GPS receiver may be used for supplemental navigation
guidance only. ILS approaches, for example, must be
flown by tuning an external VLOC receiver to the proper
frequency and coupling the VLOC receiver to the external
CDI (or HSI).
Figure 6-4 ‘GPS’ Designations
Once an approach is selected, it may be activated
for navigation from the
Procedures Page. Activating the
approach overrides the ‘enroute’ portion of the active
flight plan, proceeding directly to the ‘approach’ portion
(for a full approach, directly to the initial approach fix).
Activating the approach also initiates automatic CDI
scaling transition as the approach progresses.
Activating an approach:
1) Press the
PROC
Key to display the Procedures
Page (Figure 6-5).
2) Turn the large
right
knob to highlight ‘Activate
Approach?’ (Figure 6-5) and press the
ENT
Key.

3) A confirmation widow will appear (Figure 6-6).
With ‘Yes?’ highlighted, press the
ENT
Key.
