The Effect of Experience on Subjective Ratings for Aircraft and Simulator Workload during IFR Flight

This research is the result of a need to evaluate the effect of new complex cockpit systems on pilot workload. The goal of this research is to determine if the Pilot Objective/Subjective Workload Assessment Technique (POSWAT) ratings of workload obtained in a simulator are comparable to ratings obtained in an aircraft. In this study twenty experienced instrument rated subject pilots flew the same three simulated instrument cross-country flights. During these flights the pilots gave POSWAT workload ratings at one-minute intervals. The results show, that in general increased experience decreases POSWAT workload ratings for a given taskload.
