Prediction and Quickening in Perspective Flight Displays for Curved Landing Approaches

Abstract

In an empirical test of various predictor and quickened display algorithms eighteen professional pilot-subjects made four curved-path landing approaches in a Gat-2 simulator using each of 14 dynamically different display configurations in a within-subject design. Results indicate that second- and third-order predictor displays provide the best lateral performance. Intermediate levels of prediction and quickening provide best vertical control. Predictor-quickening algorithms of increasing computational order signficantly reduce aileron, rudder, and elevator control responses, reflecting successive reductions in cockpit workload. Whereas conventional crosspointer displays are not adequate for curved landing approaches, perspective displays with predictors and some vertical dimension quickening are highly effective.
