“…The Terminal Area Capacity Enhancement Concept (TACEC) expands on Rossow's ideas by considering new technologies that allow the system to work in IMC while minimizing blunders and collision risks. 13,14,1516 The TACEC system will allow up to four commercial aircraft to fly in close formation during final approach and land on very closely spaced parallel runways † (VCSPR) while on autopilot. 17 The TACEC system is under development with a goal for implementation in 2022.…”

Large Eddy Simulations are used to examine wake interactions from aircraft on closely spaced parallel paths. Two sets of experiments are conducted, with the first set examining wake interactions out of ground effect (OGE) and the second set for in ground effect (IGE). The initial wake field for each aircraft represents a rolled-up wake vortex pair generated by a B-747. Parametric sets include wake interactions from aircraft pairs with lateral separations of 400, 500, 600, and 750 ft. The simulation of a wake from a single aircraft is used as baseline. The study shows that wake vortices from either a pair or a formation of B-747's that fly with very close lateral spacing, last longer than those from an isolated B-747. For OGE, the inner vortices between the pair of aircraft, ascend, link and quickly dissipate, leaving the outer vortices to decay and descend slowly. For the IGE scenario, the inner vortices ascend and last longer, while the outer vortices decay from ground interaction at a rate similar to that expected from an isolated aircraft. Both OGE and IGE scenarios produce longer-lasting wakes for aircraft with separations less than 600 ft. The results are significant because concepts to increase airport capacity have been proposed that assume either aircraft formations and/or aircraft pairs landing on very closely spaced runways.

“…One approach that has been defined by the International Civil Aviation Organization (ICAO) and the certification of the necessary avionics supported by the FAA is VHF Data Link Mode 3 (VDL Mode3). We have evaluated in [5] whether a system having characteristics similar to VDL Mode 3 could support this application. The essential features of VDL Mode 3 are the time division multiple access protocol providing four subchannels for user information and a separate management channel.…”

“…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.…”

Guidelines for Avoiding Vortex Wakes During Use of Closely-Spaced Parallel Runways

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.
