Abstract : The present investigation had three major objectives: (1) Develop software that provides a robust and sensitive set of flight-relevant tasks. (2) Provide operator performance data for each flight task under normal (manual), single-task conditions (3) Evaluate the sensitivity of operator performance on each task to changes in task difficulty and in the number and type of concurrent tasks performed. The overall goal was to provide an empirical 'baseline' from which the results of future adaptive-automation studies (in which task difficulty and operator workload would vary) could be successfully interpreted. Overall, the three studies were successful in meeting the first major goal of the adaptive automation research program: to establish a baseline of empirical performance data in a multi-task flight-simulation environment. These results will help in the design and interpretation of results of future adaptive- automation studies that will be carried out as part of this research program.
