Since July 1973 there have been eight U.S. air carrier accidents attributed to encounters with strong low-level wind shears during terminal flight operations. The FAA research and development effort has taken a threefold approach to the wind shear problem 1 developing and implementing improved forecasting techniques and procedures for predicting and reporting low-level wind shear in the terminal area 2 placing wind shear detection equipment on the ground and transmitting information to the pilot and 3 installing equipment aboard the aircraft that would provide the pilot with wind shear information in real time. The results of the latter effort, i.e., airborne wind shear systems and techniques are evaluated as to their relative benefits and costs both to the user and to the FAA. Ground speed is a major input variable to many of the candidate airborne wind shear systems. Eight techniques for providing ground speed are evaluated and cost comparisons are documented. Also evaluated are three self contained wind shear systems that do not rely on ground speed as a reference and a head-up display for displaying wind shear data. Author
