Nearest Airspace Page
The last page in the NRST group, the nearest air-

or special use airspaces near or in your flight path. 
Alerts are provided according to the following condi-
tions: 
•  If your projected course will take you inside an 
airspace within the next ten minutes, the alert 
message “Airspace ahead -- less than 10 min-
utes” will appear. The nearest airspace page will 
show the airspace as “Ahead”. 
•  If you are within two nautical miles of an airspace 
and your current course will take you inside, the 
message “Airspace near and ahead” will appear. 
The nearest airspace page will show “Within 2nm 
of airspace”. 
•  If you are within two nautical miles of an airspace 
and your current course will not take you inside, 
the message “Near airspace less than 2nm” will 
appear. The nearest airspace page will show the 
airspace as “Ahead < 2nm”. 
•  If you have entered an airspace, the message 
“Inside Airspace” will appear. The nearest air-
space page will show “Inside of airspace”.

Note that the airspace alerts are based on three-
dimensional data (latitude, longitude and altitude) to 
avoid nuisance alerts. The alert boundaries for con-
trolled airspace are also sectorized to provide complete 
information on any nearby airspace. Once one of the 
described conditions exists, the message annunciator 
will flash, alerting you of an airspace message.

Once you have been provided an airspace alert 
message, detailed information concerning the specific 
airspace is provided on the nearest airspace page. The 
nearest airspace page displays the airspace name, status 
(“Ahead”, “Ahead < 2nm”, etc. as described on the 
previous page), and a time to entry (if applicable). By 
selecting any airspace name listed on the nearest air-
space page, additional details will be provided—includ-
ing controlling agency, communication frequencies 
and floor/ceiling limits.

Ident, Volume  and Tuning
Section 8   
VLOC (VOR/Localizer/Glideslope) 
Receiver Operations
The GNS 430W includes digitally-
tuned VOR/localizer and glideslope receiv-
ers with the desired frequency selected on 
a VLOC window, along the left-hand side 
of the display. Frequency selection is performed by 
pressing the small left knob and turning the small 
and large left knobs to select the desired frequency. 
Ident Audio and Volume
VLOC ident is enabled by pressing the 
VLOC volume knob. When VLOC ident 
is enabled, an “ID” indication appears 
in the upper right corner of the VLOC 
window — to the immediate right of “VLOC”. 
jPush for ident audio. Turn to adjust audio volume. 
VLOC audio volume is adjusted using the VLOC 
volume knob. Turn the VLOC volume knob clock-
wise to increase volume, or counterclockwise to 
decrease volume. 
VLOC Window and Tuning
VLOC frequencies are selected with the tuning 
cursor in the standby VLOC frequency field, and using 
the small and large left knobs to dial in the desired 
frequency. The standby frequency always appears 
below the active frequency. The active frequency is the 
frequency currently in use. 
Turn to adjust the MHz value (the 
portion before the decimal point)  of the standby VLOC frequency. 
v
Push to toggle the tuning cursor (small left knob) between COM 
and VLOC windows. Turn to adjust  the kHz value (the portion after the decimal point) of standby  VLOC frequency. 
y
The tuning cursor will remain in the COM window. 
If you wish to select a VOR/localizer/ILS frequency, 
press the small left knob momentarily to place the 
cursor in the VLOC window. 
 NOTE: The tuning cursor will normally appear 
in the COM window, unless placed in the VLOC 
window by pressing the small left knob. When 
the tuning cursor is in the VLOC window, it will 
automatically return to the COM window after 30 
seconds of inactivity.

Auto-Tuning
To select a VOR/localizer/ILS frequency: 
1.   If the tuning cursor is not currently in the VLOC 
window, press the small left knob momen-
tarily. 
2.   Turn the large left knob to select the desired 
megahertz (MHz) value. For example, the 
“117” portion of the frequency “117.80”. 
3.   Turn the small left knob to select the desired 
kilohertz (kHz) value. For example, the “.80” 
portion of the frequency “117.80”. 
4.   To make the standby frequency the active 
frequency, press the VLOC flip-flop key. 
Auto-Tuning
A frequency may also be quickly selected from the 
database by simply highlighting the desired frequency 
on the VOR page or the nearest VOR page and pressing 
the ENT key. This process is referred to as auto-tuning. 
Once a frequency is selected in the standby field, it 
may be transferred to the active frequency by press-
ing the VLOC flip-flop key. (Auto-tuning can also 
be performed from VLOC frequencies listed on the 
NAVCOM, airport frequency, and nearest flight service 
station pages.) 
To select a VLOC frequency from the VOR or near-
est VOR  pages: 
1.   Select the desired page from the main  pages. 
(See page references on the preceding page.) 
2.  Press  the small right knob momentarily to 
activate the flashing cursor. 
3.  Turn  the large right knob to highlight the 
frequency for the desired VOR. 
4.  Press ENT to place the frequency in the standby 
field of the VLOC window. 
5.  Press the VLOC flip-flop key to activate the 
selected frequency.
