AIRCRAFT WAKE VORTEX TAKEOFF TESTS AT TORONTO INTERNATIONAL AIRPORT

This report describes the collection and analysis of data related to the behavior of the wake vortices of departing aircraft. The test site was located on the departure end of Runway 23L at Toronto International Airport, Toronto, Ontario, Canada. Three arrays of Ground Wind Vortex Sensing Systems and one Monostatic Acoustic Vortex Sensing System were used to detect, track and measure the strength of the vortices. The data were analyzed to determine vortex lifetimes, transport characteristics and decay mechanism. The results of the data analysis were used to generate an elliptical wind rose criterion similar to that used in the Vortex Advisory System for reduction in interarrival aircraft spacings. (Author)
