Model Descriptions

This guide covers the operation of the GPS 400W,
GNC 420W, GNC 420AW, GNS 430W, GNS 430AW.
In general, all models will be referred to as the 400W-
series, except where there are physical or operational
differences. The 400W-series units are 6.25" wide and
2.66" high. The display is a 240 by 128 pixel color LCD.
The units include two removable data cards, one with
a Jeppesen database (inserted in the left-most card slot)
and the second being a Terrain database (inserted in the
right-most card slot).

GPS 400W

The GPS 400W has a WAAS GPS engine and is TSO
C146a certified for primary domestic, oceanic, and
remote navigation including en route, terminal, and
non-precision approaches, and approaches with vertical
guidance, such as LPV and LNAV/VNAV. The GPS 400W
can simultaneously give aviators vital approach infor-
mation and weather and traffic data in relation to their
position on a color moving map display. Thanks to a
high-contrast color display, the information can be easily
read from wide viewing angles even in direct sunlight. Its
color moving map features a built-in database that shows
cities, highways, railroads, rivers, lakes, coastlines, and a
complete Jeppesen database. The huge Jeppesen database
(that can be updated with a front-loading data card)
contains all airports, VORs, NDBs, Intersections, FSS,
Approach, DPs/STARs, and SUA information.
Pilots will enjoy the GPS 400W as an MFD, especially
when it is coupled with traffic, lightning detection, and
weather interfaces like Ryan TCAD, TIS from the Garmin
GTX 330 Mode S transponder, or L3 SKYWATCH™, or
STORMSCOPE ® WX 500. With the PC-based FDE pre-
diction program, the GPS 400W may be used for oceanic
or remote operations. For the latest in graphical and
textual weather information, the GPS 400W can connect
to XM Satellite Radio' s XM WX Weather Service via the
GDL 69/69A datalink receiver.
