The flight trials of the ALFLEX (Automatic Landing Flight Experiment) vehicle were successfully concluded on August 15, 1996, at Woomera Airfield in South Australia. The flight trials were held in winter under especially bad weather conditions such as cross winds and tail winds for the AFLEX vehicle approaching runway 18. This paper describes the technique of making flight GO-NOGO decisions according to wind restrictions for ALFLEX trials based on both the wind speed data of Real Time Vector Representation Equipment (RTVRE) of surface wind and analysis of upper surface wind measurements data using OMEGA SONDE and GPS SONDE. It also compares these wind measurement results with the wind speed estimated using ADS and IMU sensors that were onboard the ALFLEX vehicle.
