The FAA plans to transition the U.S. National Airspace System (NAS) navigation infrastructure to enable performance-based navigation (PBN) as part of the Next Generation Air Transportation System (NextGen). The FAA plans to transition from defining airways, routes and procedures using VHF Omni-directional Range (VOR) and other legacy navigation aids towards a NAS based on Area Navigation (RNAV) everywhere and Required Navigation Performance (RNP) where ben-eficial. Such capabilities will be enabled largely by the Global Positioning System (GPS) and its augmentations such as the Wide Area Augmentation System (WAAS) and Ground Based Aug-mentation System (GBAS). As a result of this transition, the need for ground-based navigation services will diminish, and the number of federally provided ground-based facilities will be re-duced accordingly, but with sufficient time for users to equip with SATNAV avionics.
