Manufacturer: GARMIN

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 that features a WAAS-certified GPS, 2280-channel capacity comm and 200-channel ILS/VOR with localizer and glideslope. High-speed 5 Hz processing makes navigation calculations and map redraw rates 5 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. They can also share user waypoints 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 5 position updates per second, GNS 430W meets stringent TSO C146a FAA standards for WAAS "sole means" navigation — providing vertical and lateral approach guidance into thousands of U.S. airports previously inaccessible in IFR conditions.

High Resolution Mapping

Its 4" 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 and approach procedures. 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. Its 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 and coastlines. With information from the built-in terrain and U.S. obstacles databases, it uses color coding to graphically alert you when proximity conflicts loom.

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 interfaces with an 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 and TAFs. With an optional subscription to XM WX Satellite Weather and the addition of a GDL™ 69 series datalink receiver, you’ll have access to high resolution weather for the U.S., right in the cockpit. NEXRAD, METARs, TAFs and lightning information can be overlaid on Jeppesen and topographic map databases. With an additional subscription, GDL 69A delivers SiriusXM Satellite Radio to your aircraft. Add the GTX 330 Mode S transponder, and GNS 430W will also display Traffic Information Services (TIS) alerts that identify surrounding air traffic.
