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.
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.
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.
