The testing of the operational performance of the airborne, infrared wind shear sensing system entailed aircraft flights in and through light and moderate rain. The system has been flown primarily only in clear conditions. The algorithms applied to the radiometer output for shear alert processing that had functioned in clear conditions were applied in rain obscuration. The airborne, infrared shear detection and avoidance system produced an 87 percent success rate in detecting low altitude shear before encounters from 40 to 60 seconds prior to the eight encounters. All events occurred during light and some moderate rain. The false alarm rate for eleven no-shear flights was 18 percent but we believe it can be improved with a scanning and multiple filter system.
