SECTION 1
INTRODUCTION
Selecting COM and VLOC Frequencies
While the GNS 430 is acquiring a position, take a
minute to dial in the active and standby frequencies to
be used for the first phase of the flight. The GNS 430’s
display is divided into separate ‘windows’ (or screen
areas), including a COM Window, VLOC Window, and
the GPS Window (Figure 1-11).

Pressing the small left knob activates the tuning cur-
sor in the desired frequency window. To select the active
frequency, first enter the frequency in the standby field,
and use the
COM Flip-flop (or the NAV Flip-flop ) Key
to move it to the active field.
To change the standby communication
frequency:
1) Press the small left knob if needed, to move
the tuning cursor to the COM Window (Figure
1-11).
2) Turn the large left knob to select the MHz,
and the small
left
knob to select the kHz of
the desired frequency.
To place the standby communication
frequency in the active field:
Press the COM Flip-flop Key (Figure 1-12).

Once the active frequency has been entered, repeat
steps 1 and 2 to enter the standby frequency. After both
communication frequencies have been entered, the COM
Window may be kept ‘hot’ by leaving the cursor on the
standby frequency. Move the cursor to the VLOC Window
by pressing the small
left knob.
NOTE: When selecting VLOC frequencies, the
tuning cursor automatically returns to the COM
Window after 30 seconds of inactivity.
To change the standby VLOC frequency:
1) Press the small left knob if needed, to activate
the tuning cursor in the VLOC Window.
2) Turn the large
left
knob to select the MHz,
and the small
left
knob to select the kHz of
the desired frequency.
To place the standby frequency in the
active field:
Press the NAV Flip-flop Key.
