| Abstract | Preliminary tests conducted by WLR Research in the Fall of 1993 showed considerable promise that a Radio Acoustic Sounding System (RASS) was capable of detecting and tracking wake vortices located in the approach glide slope. Initial testing of the RASS created interest in the possibility of a relatively low cost RASS monitoring the entire approach glide slope out to the middle market. As a result of the optimistic results of the initial tests, the Federal Aviation Administration (FAA) Wake Vortex Program Office decided to fund additional testing of the RASS to resolve some remaining questions and to evaluate its performance in detecting wake vortices in both the longitudinal (along the approach path) and transverse (perpendicular to the approach path) modes. The purpose of this test program was to validate the longitudinal and transverse mode RASS capabilities to: (1) indicate vortex presence in the flight path during a variety of meteorological conditions and (2) track a vortex or pair of vortices during a variety of meteorological conditions. |
