  • To predict the changes of situation awareness for the pilot, a new quantitative situation awareness model and solving method, which considered the influence of information importance on situation awareness, the characteristics of human cognition and the Bayesian conditional probability theory, was proposed based on the attention allocation model and the situation awareness model built previously. In order to verify the validity of the model, 20 subjects performed an instrument supervision task under different task conditions. Situation awareness global assessment technique (SAGAT), 3-dimensional situational awareness rating technique (3-D SART), performance measure and eye movement measure were adopted for evaluating the situation awareness under different task conditions. The integrated experimental results reveal that the changing trend of situation awareness calculated by the model is highly correlated with the practical experimental results. This new quantitative situation awareness model will provide a reference for the optimization design of the cockpit display interface and the research of reducing the human error.
