the frequency. Additional information on approach
procedures is provided in Section 5.
To select an approach and automatically tune the
proper VLOC frequency:
1. Select the destination airport using the direct-
to key or as the last waypoint in the active
flight plan.
2. Press the PROC key to display the procedures
page.
3. Turn the large right knob to highlight “Select
Approach?” and press ENT.
4. A window will appear listing the available pro-
cedures. Turn the small right knob to highlight
the desired procedure and press ENT. (When
a direct-to destination is selected, departures
are offered for the nearest airport.)
5. A second window will appear listing available
transitions. Turn the small right knob to
highlight the desired transition waypoint and
press ENT. (The approach “Vectors” option
assumes you will receive vectors to the final
course segment of the approach and will
provide navigation guidance to intercept this
final course.)
6. Turn the large right knob to highlight “Load?”
or “Activate?” and press ENT. (“Load?” will
add the procedure to the flight plan without
immediately using it for navigation guidance.
This allows you to continue navigating the
original flight plan, but keeps the procedure
available on the active flight plan page for
quick activation when needed.)
7. For VOR and ILS approaches, the standby field
of the VLOC window is automatically tuned to
the proper frequency. To activate the frequency
press the VLOC flip-flop key. To display VLOC
course information on the external CDI (or HSI)
press CDI and verify that “VLOC” is displayed
at the bottom left corner of the screen, directly
above the CDI key.
