A Multiple-Regression Model of Pilot Performance in Vertical and Translational Flight
Abstract
An experiment was conducted to advance the development of a multiple regression model of VTOL pilot performance as a function of various control/ display system and flight mission variables. Second-order response surfaces as a function of two control system design variables (translational control order and vertical control gain reduction factor) and three downward-looking display design variables (horizontal position error magnification, translational prediction time, and translational tracking mode) were derived from Pilot performances on each of three mission scenarios. The optimum values for each of the five system design variables were determined for each scenario independently using the same central composite experimental design with three groups of four subjects each. Comprehensive analyses of variance and canonical analyses were used to refine the fitted surfaces to determine the true nature of the pilot performance effects for each flight scenario and to select a single set of system design parameters that would yield near-optimum performances on all three scenarios. Keywords: Helicopter flight instrumentation; VTOL flight instrumentation; Computer graphic displays; Contact analog displays; Frequency- separated displays; Predictor displays; Horizontal situation displays; Vertical situation displays; Translational flight; Vertical flight.
