Abstract

The objectives of this study were to develop an engineering model of pilotage performance times in actuating switches and to test the feasibility of its use in task time-line analysis. A low-fidelity environment was simulated. Compensatory tracking was used to approximate the concurrent task of aircraft control corrections to turbulence during straight-level flight. Variables that affected time and tracking performance were identified for use to predicting performance. Several desired features of switch-actuation performance times were investigated for prediction purposes. Our experimental results confirmed that the most needed and desired features existed or were well approximated for estimating performance times in these analyses for use during early stages of aircraft design. The engineering model should offer improved efficiency to task time-line analysis. Tracking errors were analyzed to estimate the vision and attention requirements of the variations in switch-actuation tasks.
