## Abstract

Under Special Federal Aviation Regulation (SFAR) No. 97, the FAA allows the use of Global Positioning System/Wide Area Augmentation Systems for the en route portion of flights on routes in Alaska outside the operational service volume of ground based navigation aids. The use of aircraft navigation equipment other than area navigation systems, that only permit navigation to or from ground-based navigation stations, often results in less than optimal routes or instrument procedures and an inefficient use of airspace. SFAR 97 optimizes routes and instrument procedures and provides for a more efficient use of airspace. Further, the FAA anticipates that it will result in an associated increase in flight safety.
