An investigation was conducted jointly by the FAA and NASA to determine the radial extent of the circulatory flow field around the lift-induced vortex system of an aircraft in flight. This flow field, if found to be of sufficient strength and span to activate instrumentation onboard a following aircraft, may provide the basis for designing a feasible airborne wake detection and avoidance system. A small probe aircraft was flown behind a larger wake generator aircraft to measure the lateral separation distance at which the vortex could be detected using conventional instrumentation. This report discusses the results and mechanics of the flight test and proposes recommendations for future tests. (AN).
