“…The results presented assume that the transition from a VMC to an IMC capability at airports has been completed. [21][22][23][24][25][26][27][28][29][30][31][32][33] For a number of operational reasons, success with wake-avoidance technologies will have been achieved when the safe zone for the along-trail separation distance, or time between the two aircraft, can be safely increased from nearly simultaneous (or 5 s, i.e., about 1000 ft or 305 m) to as much as 10 s (about 2000 ft or 610 m) or more. The larger along-trail separation distances facilitate wave-off operations and accommodate required aircraft-grouping combinations.…”

This paper proposes a reliable method for estimation of the movement and spread of lift-generated vortex wakes as a function of time to better enable aircraft arriving at airports to avoid the hazards associated with the wakes of preceding aircraft. Operations on closely-spaced parallel runways illustrate how the method may be applied. An overview presents the aerodynamic mechanisms that cause the hazardous parts of lift-generated wakes to spread as a function of time. A computational method developed for determination of the spread of vortex wakes as a function of time is then applied to operations of aircraft as they approach closely-spaced parallel runways. The results suggest guidelines for efficiently and effectively avoiding the vortex wakes of preceding aircraft. Because the theoretical tools developed and the measurements of the components of the time-averaged wind and its gust magnitudes contain uncertainties, flight tests are recommended to confirm and to refine the guidelines presented, and to verify the techniques used to measure the atmospheric parameters that control wake intrusion.

“…1 Another part of the foregoing research program was directed at finding effective and efficient ways to avoid the vortex wakes of preceding aircraft. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] The present research effort does not attempt to reduce the in-trail time between aircraft landing on the same runway, because the increase [2][3][4][5][6] in airport capacity to be achieved is less than about 10%. In contrast, it is estimated that the capacity of airports can be safely increased by a factor of two or more by use of an improved wake-avoidance method for airport operations on sets of closely-spaced parallel runways.…”
