Selecting COM and VLOC Frequencies
While the 400W-series unit 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 400W-series display is divided into separate
“windows” (or screen areas), including a COM window,
VLOC window, and the GPS window.
COM Window:
Active Frequency
COM Window:
Standby Frequency
with tuning cursor
VLOC Window:
Active Frequency
Pushing the
small left
knob activates the tuning
cursor in the desired frequency window. To select the
active frequency, you must first enter the frequency
in the standby field, and use the
COM flip-flop
(or
VLOC flip-flop
)
key to move it to the active field.
To change the standby communication (COM) or
VLOC frequency:
1. If the tunng cursor s not currently n the
desred wndow (COM or VLOC), press the
small left
knob momentarly to swtch the
hghlght between the COM and VLOC wn-
dows. Adjustng the frequences wth the
large
and
small left
knobs wll affect the standby
frequency.
2. Turn the
large left
knob to select the desred
megahertz (MHz) value. For example, the
“135” porton of the frequency “135.325”.
3. Turn the
small left
knob to select the desred
klohertz (kHz) value. For example, the “.325”
porton of the frequency “135.325”.
4. To actvate the selected frequency, press the
approprate
flip-flop
key—COM for commu-
ncaton frequences or VLOC for VOR/Localzer
frequences.
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.
Once you’ve entered the active frequency, simply
repeat steps 1 to 3, above, to enter the standby fre-
quency. 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.
These features are only available in the 420W/430W
units.
