This paper discusses a concept called ldquopaired approachesrdquo which is designed to facilitate approaches to closely spaced parallel runways (CSPRs) - i.e., runways separated by 700 ft to 2500 ft, in instrument meteorological conditions (IMC). Such runway pairs experience a significant loss of arrival capacity during IMC and marginal visual conditions(More)

Air traffic is expected to increase significantly over the next ten to fifteen years, doubling by some estimates. A major challenge for supporting this type of growth is the arrival and departure capacity at major airports. There are many initiatives working to improve the arrival capacities at these airports, but very few enable corresponding increases in(More)
The FAA and NASA are jointly embarking on a multiphased research and development program to develop and implement wake vortex avoidance solutions that can safely reduce separations and improve capacity at airports in the NAS. Many options have been proposed by the wake turbulence community and it is necessary to focus research efforts on the most promising(More)
As NextGen concepts move toward increasing en route and terminal throughput, wake turbulence separation may become a limiting factor in the pursuit of capacity improvements. Better knowledge of the probable location of wakes (for air traffic controllers as well as pilots) could help provide safe separation from wake turbulence while avoiding unnecessary(More)
