Wind Effects on the Lateral Motion of Wake Vortices

Abstract

This report examines the influence of crosswind and other factors on the behavior of wake vortices. Data from acoustic remote sensors and in situ sensors were used to track the possible transport of wake vortices between parallel runways. The measurements used in the analysis came from landing (1976-7) and takeoff (1980) operations at O'Hare International Airport. As expected, wake vortices are observed to transport with the ambient wind; therefore, dangerous wake vortex encounters can be avoided on parallel runways with suitable assignment of aircraft to the two runways. The analyses of the report were carried Out in the mid 1980s and serve to document the O'Hare landing and takeoff databases and how they can be used. The status of the acoustic and in situ wake vortex sensors is updated to the late 1990s.
