The Dichotomy

Frank L. Frisbie

Abstract:	The U.S. National Airspace System (NAS) ground infrastructure is being upgraded to take advantage of the benefits of GPS/GNSS. The upgrades are detailed in the NAS Architecture which had broad support. The author contends, however, that the lesson of history is being ignored. Citing some of that history, the paper makes the point that the effectiveness of these improvements is critically dependent upon consistent upgrades to user electronics (avionics). Absent some new strategy to make the commercial, private and military users of the air space system buy and install the new avionics equipment, major improvements in system performance can not be achieved. The paper offers one such strategy and encourages a greater degree of Federal Aviation Administration (FAA) control over user equipment.
