ILS Approach
430W Only
1. Select the departure (CSTL1) from the pro-
cedures page. Then select the departure
runway (RW02, in this example) and transition
(GEDIC).
2. As you depart the airfield, “NEXT DTK 026°”
appears in the lower right corner of the screen
and “SUSP” appears directly above the
OBS
key. You are now on the “course from fix to
manual sequence” leg. The distance displayed
on the active flight plan, default NAV and map
pages is FROM the waypoint fix (the departure
runway, in this example).
3. Fly the outbound course keeping the CDI needle
centered. Once you are cleared to sequence to
the next leg, press the
OBS
key. Confirm that
“SUSP” no longer appears directly above the
OBS
key. An alert (“NEXT DTK 183°”) will
appear in the lower right corner of the screen
to guide you to the next waypoint (HFD VOR).
The actual desired track (DTK) will depend on
your ground speed and distance from HFD
VOR.
4. Once the
OBS
key is pressed, the 400W-series
unit will automatically sequence to each
waypoint along the remainder of the departure
route, including the selected transition.
ILS Approaches
Precision approaches can be performed with the
GNS 430W’s built-in VLOC (VOR/localizer/glideslope)
receivers. The GPS receiver can be used for guidance
prior to reaching the final approach fix, but once
there, the proper frequency must be selected on the
VLOC window (left side of screen) and the CDI output
set to “VLOC”.
The GNS 430W can be set to automatically switch
the external CDI output from GPS to VLOC as you
intercept the final approach course (if used with a
KAP140/KFC225 autopilot, you will need to manu-
ally enable outputs). See instructions at the end of this
section. When the ILS approach is activated, the GNS
430W will automatically switch within 1.2 NM left or
right of the final approach course. This switch can take
place anywhere from 2.0 to 15.0 NM from the FAF.
The illustration at right shows multiple locations
along the approach path and which CDI selection
you can expect: GPS or VLOC. Within the area of the
shaded box, the automatic switch from GPS to VLOC
should occur.
NOTE:
If you attempt to intercept the approach
course at a distance less than 2.0 NM from the
FAF, the GNS 430W will not automatically switch
the CDI to VLOC. In this case, press the CDI key to
manually switch from GPS to VLOC.
