• Abstract:
  This report addresses the wake-turbulence separation standards for close-spaced parallel runways. Ground-wind anemometer data collected at Kennedy (landing) and O'Hare (takeoff) airports are analyzed to assess the lateral transport probability for wake vortices. A model is developed to predict the lateral transport probability and is used to analyze possible reductions in the wake-turbulence limits on parallel runways for reduced ranges of aircraft classes (e.g. only Small and Large aircraft). Unfortunately, adoption of the calculated reduced separation standards cannot be recommended because of uncertainties in the analysis.
