6.  Press  the small right knob to remove the 
flashing cursor. 
 NOTE: For duplex COM operations, the VLOC re-
ceiver may be auto-tuned from the nearest flight 
service station page. 
When selecting a VOR or ILS approach, manual 
tuning of the VLOC receiver is not required. Once 
the approach procedure is “Loaded” or “Acti-
vated”, the GNS 430W will automatically place 
the proper frequency in the standby field of the 
VLOC window. If you wish to use this frequency, 
simply press the...

8.     For precision approaches and some non-
precision approaches, a reminder window will

groups—NAV, WPT, AUX, NRST—and described each 
page in the NAV group. The third page group (AUX) 
allows you to change unit settings, customizing opera-
tion to your preferences. The AUX pages also provide 
E6B functions—such as trip planning, fuel planning, 
density altitude, true airspeed and winds aloft calcula-
tions. 
To quickly select an AUX page:

Flight Planning Page
The flight planning page provides access to E6B 
functions for fuel planning, trip planning, density 
altitude/true airspeed/winds aloft calculations and 
a “Crossfill” function to transfer flight plans/user 
waypoints to a second 400W-series unit. When a flight 
planning item is selected, the corresponding page will 
appear providing additional information and features. 
To select, highlight with cursor and  press ENT

Flight Planning
Density Alt / TAS / Winds— indicates the theo-
retical altitude at which your aircraft will perform 
depending upon several environmental conditions, 
including indicated altitude (IND ALT), barometric 
setting (BARO) and total air temperature (TAT; the 
temperature, including the heating effect of speed, 
read on a standard outside temperature gauge). 
This computes true airspeed (TAS), based upon the 
factors above and the calibrated airspeed (CAS). 
Also, this determines winds...

 NOTE: Fuel planning figures can be entered 
and displayed based upon one of three possible 
configurations:   
 
1) No fuel sensors connected—In this instance 
fuel flow is manually entered and is used to 
calculate fuel on board. When fuel flow or fuel 
on board is manually entered, the figures are 
retained the next time you view the page (with 
fuel on board continuously recalculated).
