QUANTITATIVE MEASUREMENT OF OBSERVED WORKLOAD IN THE ANALYSIS OF AIRCREW PERFORMANCE

A methodology for the quantitative evaluation of observed workload was proposed. The model was designed to provide point estimations of obse rved workload at any time during the performance of a set of tasks. Th e model was also designed to provide information about the task-schedu ling strategies used to complete a set of tasks. The proposed model wa s then tested with data from a full mission flight simulation. The mod el predictions correlated significantly with expert ratings of workloa d management made during the flight simulation. The model was also abl e to distinguish between low- and high-performing aircrews when perfor mance was based on the number of errors made during flight simulations .
