Abstract:

This investigation was conducted to document changes in pilot performance and activity resulting from augmentation of the helicopter yaw axis. Subject pilot opinions regarding workload and pilot acceptance of the concept of yaw augmentation were also evaluated. Eight highly qualified instructor pilots were used as data collection pilots. These pilots flew profiles representing typical helicopter instrument maneuvers. Each maneuver, except for the instrument takeoff flown augmented only, was flown first with the yaw-augmentation system engaged and then repeated without yaw-augmentation. Objective and subjective data was obtained through the use of video, audio, oscillograph recording equipment and in-flight and postflight questionnaires and debriefings. Due to the lack of large scale computer facilities for objective data analysis, an interim report is being published. A final report utilizing correlation and regression analysis, documenting cause and effect relationships will be published when computer facilities are available. The present interim report provides limited objective data analysis and project personnel interpretation of the subjective data. Author
