Modeling human tracking performance in a high G-stress environment

Simulated air-to-air compensatory tracking experiments, using both fixed and moving base simulations, have been conducted at the Aerospace Medical Research Laboratories (AMRL), Wright-Patterson Air Force Base (WPAFB), Ohio. The recorded data consisted of time-histories of longitudinal tracking error, pilot stick input, attained vertical acceleration (+GZ) and other auxiliary variables. These data time-histories were averaged across repetitive runs to obtain first- and second-order ensemble statistics. In the present study, modeling efforts that would replicate the experimental data are attempted by applying the Optimal Control Model (OCM) to the human operator (HO) under normal and high-GZ stress conditions.
