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. 

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. 

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.
