A Comparison of Active Sidestick and Conventional Inceptors for Helicopter Flight Envelope Tactile Cueing

This paper will compare the results of two ground-based piloted simulation studies of helicopter flight envelope tactile cueing. The objective of these trials was to develop methods of assisting the pilot in respecting flight envelope limits in a high workload environment. Both trials looked at the same aggressive hover and forward-flight tasks, the difference being that in the first trial, large-displacement programmable force-feel inceptors were used while in the second programmable short active sidesticks were used.
