Zusammenfassung:The Rosemount low range orthogonal airspeed system with a Model 853G sensor installed above the main rotor was evaluated by the United States Army Aviation Engineering Flight Activity at Edwards Air Force Base, California, in August 1976. The system repeatably measured airspeed in the direction of the relative wind. However, the system had excessive perturbations in the axis perpendicular to relative wind, which must be corrected prior to the system becoming operational. (AUthor)
