Area navigation high-altitude network study

Abstract: A high-altitude area navigation (RNAV) network study was conducted at the National Aviation Facilities Experimental Center (NAFEC) in order to (1) apply and evaluate the FAA/Industry RNAV Task Force concepts for RNAV route structures in the high-altitude airspace, (2) offer alternative approaches, where appropriate, and (3) derive data relative to the potential benefits to the air traffic control (ATC) system and to its users by the implementation of RNAV. For design purposes, the enroute structure was based on the requirements for an all-RNAV high-altitude environment starting in 1977. Route structures were evaluated through fast time simulation of a mixed RNAV/VOR environment, with traffic samples representing projected traffic densities for the pre-1977, 1977-1982, and post-1982 time periods with varying mixes of RNAV-equipped aircraft. Alternative route structure design principles were developed which differed from the RNAV Task Force concepts in (1) the configuration of arrival and departure routing into and out of terminal areas, (2) the use of one-way routes, (3) the use of charted routes versus provision for noncharted offset tracks, (4) the treatment given to traffic from intermediate terminals with respect to nearby flows between more distant terminals, and (5) route width requirements.
