Satellite Navigation — GPS/WAAS Approaches

The availability of Wide Area Augmentation System (WAAS)-capable approach procedures is a significant enabler of WAAS benefits in the United States. This page provides the latest status of these U.S. WAAS approach procedures.

What's new?

As of January 31, 2019 there are 3,969 Wide Area Augmentation System (WAAS) Localizer Performance with Vertical guidance (LPV) approach procedures serving 1,931 airports. 1164 of these airports are Non-ILS airports.

Currently, there are also 698 Localizer Performance (LP) approach procedures in the U.S. serving 522 airports.
