Abstract
The Flight Research Simulator of the University of Toronto Institute for Aerospace Studies was modified to represent a fly-by-wire helicopter with a digital flight control system (FCS) and a side-arm controller. A smooth FCS mode selection algorithm was developed and successfully tested. The pilot/helicopter response to mode transitions was studied for formation flying and precision hover. Both normal and failure induced transitions were investigated by a group of 9 evaluation pilots. The results were obtained in the form of Cooper/Harper handling qualities ratings (HQR) and station-keeping performance measurements. It was found that for the present mode selection algorithm, the type of mode transition did not significantly influence the experimental results. However, the molde pair (initial mode combined with final molde) was found to influence both HQR's and performance.
