Abstract:
This report presents the results of a study to determine if a requirement exists for reduced route widths in the National Airspace System. The basis for this investigation was the recommendation by the FAA/Industry RNAV Task Force that provision be made for constant and reduced route widths in order to handle the anticipated growth in air traffic by allowing more routes in the same airspace and less restriction on application of parallel offsets. The recommendation included a reduction of high altitude route widths from + or - 4.0 nm in the 1977-1982 period to + or - 2.5 nm in the post-1982 period. Route width requirements for both high altitude enroute and terminal areas are quantified, based on the impact of route width on route efficiency, airspace capacity, and route length. Results of this study, which are based on analysis of specific, high traffic demand geographical areas, indicate that there is a requirement to eliminate the current splayed route widths and provide constant width routes, but that there is no requirement for reduction of route widths below a constant + or - 4 nm in the high altitude enroute structure, or below the + or -2 nm or + or -4 nm, dependent upon distance from the VORTAC, which are currently required in the terminal area.
