The WAAS-certified GNS 430W and its larger sibling, GNS 530W, lead the industry with multitasking, integrated avionics and cutting-edge WAAS navigation. The standard GNS 430W features a 10-watt comm, and for a slightly higher price, GNS 430AW delivers 16 watts of power output.

Integrate Your Avionics

GNS 430W is an all-in-one GPS/Nav/Comm solution. It features a WAAS-certified GPS, 2280-channel capacity comm and 200-channel ILS/VOR with localizer and glideslope. Traditionally it would take a host of components to provide the capabilities of this one smart box. High-speed 5 Hz processing makes navigation calculations and map redraw rates five times faster than earlier GNS series navigators. When installed alongside GTN series avionics, the GNS 430W can automatically receive flight plans from the touchscreen device. The two devices can also share user waypoints back and forth with each other.

Fly WAAS Approaches

GNS 430W comes with built-in WAAS navigation capabilities. It is approved to fly LPV “glideslope” approaches without reference to ground-based navaids of any kind. Featuring an advanced 15-channel receiver capable of five position updates per second, GNS 430W meets the FAA's stringent TSO C146a standards for WAAS "sole means" navigation — providing vertical and lateral approach guidance into thousands of U.S. airports previously inaccessible in IFR conditions.

Get High-Resolution Mapping

GNS 430W's 4-inch high-contrast display with brilliant colors makes it easy to read and interpret pilot-critical information. Effective use of color makes it easy to see your position relative to ground features, chart data, navaids, flight plan routings, approach procedures and more. Conveniently scan information from wide viewing angles, even in direct sunlight.

Enhance Situational Awareness

GNS 430W seamlessly integrates built-in terrain and navigation databases, providing a clear, concise picture of where you are and where you’re heading. The 430W's huge Jeppesen® database, updated with front-loading data cards, contains location reference for all airports, VORs, NDBs, Intersections, Flight Service Stations, published approaches, SIDs/STARs, Special Use Airspace and geopolitical boundaries. A detailed basemap clearly shows airports, cities, highways, railroads, rivers, lakes, coastlines and more. Using information from the built-in terrain and U.S. obstacles databases, the 430W displays color coding to graphically alert you when proximity conflicts loom ahead.

Put It on Autopilot

Working in tandem with standard autopilots that accept roll-steering commands, GNS 430W behaves like a high-end flight management system (FMS) and can automatically fly your aircraft through holding patterns, procedure turns and other position-critical IFR flight procedures.

Expand Your Panel Mount

GNS 430W is easy to interface with a wide array of optional sensors and tracking systems, allowing you to see and avoid hazards such as threatening weather, lightning or air traffic. With a GDL 88 Datalink, the GNS 430W can display ADS-B traffic targets using TIS-A symbology, as well as subscription-free FIS-B weather information -– including graphical NEXRAD radar, METARs, TAFs and more. With an optional subscription to XM WX Satellite Weather™ and the addition of the GDL™ 69 series datalink receiver, you’ll have access to up-to-the-minute, high resolution weather for the U.S., right in the cockpit. Information includes NEXRAD, METARs, TAFs, lightning and more and can be laid directly over Jeppesen and topographic map databases. With an additional monthly service fee, GDL 69A delivers XM Satellite Radio to your aircraft. Add the Garmin GTX 330 Mode S transponder, and GNS 430W will also display Traffic Information Services (TIS) alerts that identify surrounding air traffic.

GNS 430W: Changing the course of aviation.

¹Garmin will stop accepting orders for the GNS 430W in 2012. While availability will soon come to an end, Garmin will continue supporting the product with repair services and maintenance software releases for the foreseeable future. For customers looking to purchase a GNS product, we encourage you to check out our GTN series, which replaces our GNS products.
