GNS 430 specifications

The Garmin GNS 430 has
become known as the “one
box.” Because while many avion-

ics components offer some of the capabilities of the GNS
430, it’s the integration of so many different capabilities
into a single unit that makes the GNS 430 unique. It’s a
comm/nav/GPS with brilliant color map graphics all rolled
into one.

The GNS 430 continues in the Garmin tradition of easy
operating software. Logic prevails to make sense of massive
amounts of pilot-specific data. To access this information you
merely need to master two concentric knobs and a series of
function buttons. All backlit. All right where you’d want them.

The most striking thing about the GNS 430 is how easy

it is to read and interpret. At the heart of the on-screen
data is a user-configurable color map. Of course, you can
monitor your flight plan using navigation chart graphics.
But you can also enjoy the greatest in situational awareness
with a detailed cartography database that shows airports,
cities, political boundaries, highways, railroads, rivers, lakes
and coastlines.

At the heart of the unit is a WAAS upgradeable,
12-channel GPS receiver with a 10-watt comm. The GNS 430 "A"
offers 16-watt comm transmitting power for enhanced
performance for high altitude aircraft. All 400-series units
offer Fault Detection and Exclusion (FDE) software for
Oceanic Approval.
