Figure 1-20 NAV/COM Page
The NAV/COM Page displays the available frequencies
(communications and navigation) for the departure airport,
any enroute airports which are included in the flight plan,
and the final destination airport. When using the direct-
to function, frequencies are listed for the airport nearest to
the starting position and the destination airport.
To display the frequency list for the desired
flight plan or direct-to airport:
1) Press the small right knob to activate the
cursor on the airport identifier field (in the GPS
Window).
2) Turn the small right knob to display the list
of airports (departure, arrival, and enroute) for
the flight plan or direct-to. Continue to turn
the small right knob until the desired airport
is selected.
3) Press the ENT Key to display the frequency list
for the selected airport.
A frequency listed on the NAV/COM Page can be
quickly transferred to the standby field of the COM
Window or the VLOC Window. This time-saving process
prevents having to ‘re-key’ a frequency already displayed
elsewhere on the screen.
To select a communication or navigation
frequency:
1) Press the small right knob to activate the
cursor in the GPS Window.
2) Turn the large right knob to select the desired
frequency from the list.
3) Press the ENT Key to transfer the selected
frequency to the standby field in the COM or
VLOC Window. COM frequencies automatically
go to the standby field of the COM Window and
navigation frequencies automatically go to the
standby field of the VLOC Window, regardless
of which window is currently highlighted by
the cursor.
4) To activate the selected frequency, press the
COM or VLOC Flip-flop Key.
