CHICAGO MONOSTATIC ACOUSTIC VORTEX SENSING SYSTEM. VOLUME III. EXECUTIVE SUMMARY: DECAY OF B-707 AND DC-8 VORTICES

A Monostatic Acoustic Vortex Sensing System (MAVSS) was installed at Chicago's O'Hare International Airport to measure the strength and decay of aircraft wake vortices from landing aircraft. The MAVSS consists of an array of acoustic antennas which measure the vertical profile up to 60-m altitude of the vertical component of the wind. The decay in wake vortex strength is measured as the vortex passes over successive antennas in the array. In this volume, the results of Volume II are summarized in terms of the safety implications of categorizing all landing B-707s and DC-8s as Large aircraft.
