Garmin announced yesterday that the GNS 400/500 series have been TSO'd for lateral-precision with vertical (LPV) guidance approaches and receive GPS navigation via the Wide Area Augmentation System (WAAS). The FAA also granted approved model list STC approval, allowing the 400W/500W equipment to be installed on more than 980 makes and models of aircraft. The GNS 400/500W series joins the G1000 and GNS 480 in providing WAAS enabled navigation for aircraft.

According to Garmin, owners of GNS 400/500 series panel-mount avionics will be able to upgrade their products to meet the FAA's WAAS standards without a field approval. Garmin expects deliveries of the new GNS 430W/530W to begin in about 30 days, with upgrades beginning in January. Upgrades are available for a suggested retail price of $1,500, while the GNS 430W and GNS 530W units will sell for $10,750 and $16,495, respectively.
