EVALUATION OF THE PULSED ACOUSTIC DOPPLER WIND SHEAR SENSING SYSTEM AT DULLES INTERNATIONAL AIRPORT

This effort was directed toward the test and evaluation of the pulsed acoustic Doppler wind shear sensing system (PADWSS) to determine if the system could accurately and continuously sense windspeed and wind direction at 30-meter (100-foot) intervals from 30 to 510 meters (100 to 1,500 feet) above ground level. Three other wind shear sensing systems were used for comparison: (1) instrumented tethered balloon in close proximity, (2) instrumented aircraft flights using flat runs at various altitudes and glide slope approaches, and (3) radar wind shear sensing. It was concluded that the evaluated PADWSS system cannot be utilized on an operational basis. It was adversely affected by environmental conditions (bare trees, snow) and ground windspeeds in excess of 5 meters/second (9.72 knots). (Author)
