4.   A reminder message appears, indicating that 

GPS can only be used for approach monitor-
ing.  As mentioned, you will need to use the 
VLOC receiver for this approach. Press ENT to 
acknowledge the message. 

When you “Load?” (or “Activate?”) an ILS approach, 

the ILS frequency is automatically placed in the standby 
field of the VLOC window. To use this frequency, simply 
press the VLOC flip-flop key to place it in the active 
frequency field. 

When you “Activate?” an ILS approach, automatic 

switching of the external CDI is enabled (unless turned
off from the CDI/Alarms Page). When you are established
on the inbound course to the FAF, the external CDI
guidance  will automatically switch from “GPS” (shown 
in green text) to “VLOC” (shown in white text). If you 
have forgotten to activate the ILS frequency (step #4 below), 
automatic selection of “VLOC” will not occur. 

 

NOTE:  GPS level of service annunciations (LPV, 
ENR, etc.) are not applicable to the external CDI 
(or HSI) when VLOC is active. 

1.  Within 31 NM of KFLG, the GNS 430W will 

switch from en route mode to terminal mode 
and the CDI scale will transition from 2.0 to 
1.0 NM, full scale deflection. 

2.   If you haven’t already activated the approach 

(in steps on previous page), be sure to do so 
when cleared for the approach. 

3.   As you approach the IAF (SHUTR), a waypoint 

alert (“LT TO 030° x S”) will appear in the lower 
right corner of the screen.
