Abstract:

The objective of this study was to investigate, by means of real-time man-in-the-loop simulation techniques, piloting performance as influenced by approach-signal degradation and aircraft control-augmentation variables during IFR steep-angle approaches and landings with vertical-lift aircraft. Simulation evaluations also included aircraft-type, display-format, approach-angle, and display-quickening variables to increase the generality of study results. Variable-velocity simulations of Bell UH-1 and Ryan XV-5 aircraft were utilized as test vehicles. Interpreted within the constraints imposed by the simulations, study results indicated that increased filtering of measurement noise is beneficial during approach but may have a degrading effect during hovering flight. Generally, both flight-path error and pilot control activity increased with increased measurement noise. With one exception data trends also indicated improved performance with aircraft outer-loop control augmentation.
