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 annun-
ciated 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.
