Note: We will stop accepting orders for the GNC 420W in 2012. However, we will continue to provide repair services and maintenance software releases for the foreseeable future. See our GTN series if you're interested in products similar to the GNC series.
The GNC 420W adds a TSO-certified 760-channel comm transceiver to the GPS 400W WAAS navigation capabilities and color display, creating the first color GPS/comm in the industry. GNC 420W has all the IFR GPS and comm features of the GNS 430W minus the VOR, ILS or glideslope capability you may already have in your aircraft.
Save Space with Built-in Comm
GNC 420W delivers clear communication from its 10-watt, 760-channel VHF transceiver. It also features a high power 16-watt transmitter for high altitude turbine aircraft. With the frequency nomination feature, easily load your next com frequency into standby with the touch of a button.
Fly WAAS Approaches
GNC 420W comes with built-in WAAS navigation capabilities. It’s 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, GNC 420W 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
GNC 420W has a 4" high-contrast display with brilliant colors, making 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
GNC 420W 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. Detailed basemaps clearly show 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.
Expand Your Panel Mount
GNC 420W 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 an optional subscription to XM WX Satellite Weather and the addition of a GDL 69 or 69A datalink receiver, you’ll have access to high resolution weather for the U.S., right in the cockpit. Information includes NEXRAD, METARs, TAFs and lightning. and overlay it directly 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 GNC 420W will also display Traffic Information Services (TIS) alerts that identify surrounding air traffic.
