Abstract:

A model, which had as its aim the prediction of the effectiveness of uni-operator man-machine systems, was previously derived and amplified by Applied Psychological Services. This previous model was tested against two independent tasks drawn from Naval aviation operating experience. Reasonable conformity was found between the predictions resulting from application of the model and operational experiences. The present report describes the extension of this model to simulate two-operator systems. The two-operator model may also be employed for evaluating uni-operator systems. In Applied Psychological Services two-operator model, a high speed digital computer is used to calculate and record simulated operator performance data e.g., performance time, stress, etc. for every action of each operator and to yield an indication of system effectiveness on the basis of these simulations. After development, the model was applied to the simulation of in-flight refueling of an F8U receiver aircraft by an A4D tanker aircraft. The maneuvers and actions of the F8U pilot during approach and probe insertion as well as the concomitant actions of the tanker aircraft pilot during this flight task were simulated.
