In November 1996, a number of wake vortex and meteorological sensors were operated simultaneously in the middle marker region of Runway 31R at New York's Kennedy Airport. The vortex sensors included: 1)ground-based anemometer array, 2) cw 10-micron lidar, 3) fan-beam sodar, 4) RASS, 5) sonic anemometer, 6) scintillometer, and 7) vertical beam sodaro
Comparisons of measurements from the different sensors are presented and used to a~alyze sensor capabilities and suitability for the NASA Aircraft Vortex Spacing System (AVOSS). A number of new observations were made during this test: 1) boundary thickness under wake vortex in ground effect, 2) high time resolution in situ temperature and velocity measurements inside the vortex recirculation oval, 3) directional measurements of vortex-generated sound, and
4) the influence of aIrcraft on meteorologlcal conditions.
From July 1976 through September 1977, aircraft wake vortex data were collected on the approach to runways 14R, 27R, and 32L at O'Hare International A...
The Federal Aviation Administration (FAA) and National Aeronautics and Space Administration (NASA) have been working jointly on a phased approach to i...
