In 1993 and 1994, two manned investigations were carried out on the NLR moving base Research Flight Simulator (RFS), concerning several aspects involving the use of an advanced forward*looking windshear detection system in the final approach phase of a flight. In the first (1993) experiment, three windshear detection systems were evaluated separately, or in combination, together with three specific flight procedures, without presenting any weather (or windshear) information to the crew on a weather type of display. The three systems evaluated consisted of functional models of: a reactive windshear detection system, a non*scanning Light Detection And Ranging (LIDAR) forward*looking windshear detection system, and a ground*based Terminal Doppler Weather Radar (TDWR) system. With the latter a ground*to*air data*uplink connection to the aircraft cockpit was simulated. To assess the safety aspects involved, a safety risk model was developed. The model and experiences gained with it will be described. Furthermore, final results and conclusions of the 1993 piloted experiment are presented. In the second (1994) experiment described, a reactive and a scanning forward-looking LIDAR system werre evaluated. The latter produced coloured windshear icon information on an IFIS/NAV display, using two different concepts. The flight procedure evaluated, was coupled to a systems integrated threat*level based windshear alerting concept. Pending a full data analysis, only some preliminary results and Conclusions of this second experiment are given |
