• Abstract:
  Three wake vortex measurement systems (anemometer, acoustic doppler, and laser ; doppler) were used to collect wake vortex data from aircraft departing Runway 22L at ; Chicago's O'Hare airport for nine months in 1980. The data were analyzed to determine ; vortex decay and vortex transport probabilities. The results support the ; classification of all B-707 and DC-8 aircraft in the large wake vortex class. The ; acoustic doppler system was found to be significantly more sensitive than the ground ; anemometer system to vortices transported long distances laterally by a crosswind. ; The most efficient lateral transport was noted for crosswinds greater than seven ; knots. The horizontal and vertical ground wind signatures of a wake vortex are ; compared.
