WAAS Upgrade

The 400W/500W series of navigators with WAAS now offer many enhancements over the previous non-WAAS models. Advancements include new WAAS-enabled GPS antenna, receiver, and associated software. The 400W/500W series system complies with WAAS TSO C146a and also includes a significant hardware upgrade with a new and much faster micro-processor. A terrain database for terrain awareness is included as a standard feature and now provides even greater detail. The WAAS GPS receiver now allows you to use the 400W/500W series unit for primary navigation and use GPS with vertical guidance for LPV, L/VNAV, and LNAV+V approaches. Non-precision approaches are annunciated as LNAV approaches. The Comparison of Features Summary table provides a quick view of the differences and is followed by a more detailed description of feature changes.
