Abstract : A comprehensive theory for displays used in manual control systems is applied to the instrument-landing approach problem for helicopters. A single-articulated-rotor transport and a compound rigid-rotor attack helicopter serve as examples. A comparative analysis of manual control techniques for speed and height regulation in the approach is given. Suitable display arrangements and task performance are predicted for the better control techniques. The applications of the theory incorporate recent revisions for predicting eye scanning patterns, workload measures and preferred arrangements for combined displays as well as separated instruments. Results show how display combinations which enhance the usefulness of parafoveal perception can reduce scanning workload. Other immediate applications of the theory and areas for future research are suggested. (Author)
