• Abstract:
  Aircraft-generated wake turbulence has for years been a major factor in the air-traffic-control-imposed ; separations between aircraft during departure, transit and arrival operations conducted at airports and air ; corridors of high volume. Applied research at a global level aimed to mitigate the adverse effect of wake ; turbulence traces back to the 1970s, although fundamental research related to the wake turbulence dates ; back even further 1. The volume of research and development (R&D) documented in the literature ; since the 1970s has been impressive, but it is not until relatively recently that wake turbulence R&D has ; directly contributed to both capacity and safety improvement in terms of tangible implementations of ; operational changes. The contributors to the recent success (which is the subject of the current article) in ; wake turbulence studies are many fold, and in depth account on those factors is beyond the scope of the ; current paper, but interested readers are encouraged to contact the authors for further discussions. The ; implications as well as real term impact of the recent and ongoing wake turbulence program development ; are significant in supporting Federal Aviation Administration’s (FAA) overall goal to revitalize air ; transportation system known as the Next Generation Air Transpiration System (NextGen). FAA ; NextGen is designed to meet the expected growth of aviation in the United States, which requires a much ; higher density of aircraft operating in the nation’s airspace. Many of the NextGen efforts revolve around ; reducing the navigational uncertainty in the current system such that aircraft separation can be ; substantially improved/reduced from a navigation perspective. Increasing navigation improvement, in a ; system engineering sense, then increasingly shifts the attention to other aircraft separation factors such as ; safe revision of the wake turbulence spacing as an enabler to these high-density operations. Therefore, ; unless wake turbulence separation is appropriately addressed in the NextGen context, many of the ; NextGen trajectory based concepts would not be able to realize their full potentials 2.
