Selecting Com/Nav Frequencies
While the GNS 530W is acquiring a position,
let’s take a minute to dial in the active and standby
frequencies you’ll be using for the first phase of your
flight. The GNS 530W display is divided into separate
‘windows’ (or screen areas), including a COM window,
VLOC window (by default with VOR ident/radial, but
selectable for other data — including a traffic display)
and a GPS window which occupies the right 3/4 of the
display.
COM Window:
Active Frequency
COM Window:
Standby Frequency
(with tuning cursor)
VLOC Tuning Window and
VLOC Ident Window
(Ident Window is user-selectable)
Pushing the small left knob moves the tuning
cursor back-and-forth between the COM and VLOC
frequency windows. To select the active frequency, you
must first enter the frequency in the standby field, and
use the
COM (or VLOC ) flip-flop key to move it to
the active field.
To change the standby communication (COM) or
VLOC frequency:
1. If the tuning cursor is not currently in the
desired window (COM or VLOC), press the
small left
knob momentarily to switch the
highlight between the COM and VLOC win-
dows. Adjusting the frequencies with the
large
and
small left
knobs will affect the standby
frequency.
2. Turn the large left knob to select the desired
megahertz (MHz) value. For example, the
“117” portion of the frequency “117.70”.
3. Turn the small left knob to select the desired
kilohertz (kHz) value. For example, the “.70”
portion of the frequency “117.70”.
4. To activate the selected frequency, press the
appropriate flip-flop key—COM for commu-
nication frequencies or VLOC for VOR/Localizer
frequencies.
Once you’ve entered the active frequency, simply
repeat steps 1 through 3, above, to enter the standby
frequency. After both communication frequencies have
been entered, you may elect to keep the COM window
‘hot’ by leaving the cursor on the standby frequency, or
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.
NOTE : GPS level of service annunciations (LPV, ENR,
etc.) are not applicable to the external CDI (or HSI)
when VLOC is active.
Cursor highlights COM window.
To switch the active and standby frequen-
cies, press the COM flip-flop key. Switching
the active and standby frequencies does not
remove the cursor from the COM window.
