Garmin GNS 430 WAAS Nav/com.
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
airports previously inaccessible in IFR conditions.
