To Activate An Approach - Garmin GNS 430 Pilot's Manual & Reference

SECTION 6
PROCEDURES
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
the VLOC receivers and external 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 the VLOC receiver to the proper
frequency and coupling the VLOC receiver to the external
CDI (or HSI).

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.
