Abstract
SINTEF S203The strategic objective for the EC FP6 project HASTAC is to increase the safety in all inflight situations, particulary low visibility situations, by improving the transducers used in Air Data Computers (ADC) for aircraft applications.The results are relevant in auto pilot situations in the reduced vertical separation minima legislations of 100ft as well as in demanding manual flying situations in darkness and low visibility. Used in transponder applications, the project will give significantly increased reliability in altitude information for manual and autmated Air Traffic Control Systems. Aircraft Traffic Collision Avoidance Systems will also benefit from the more accurate and reliable altitude information, which will allow the autmated avoidance instructions to be more accurate and effective
