A study on model for assessment of mental workload of fighter pilots

Objective The purpose of this study is to build a model for assessment of mental workload of fighter pilots and check its feasibility. Methods Experiments were conducted in fighter pilots ( n =144,60 respectively) using fighter A, fighter B simulators. Seven workload indexes from subjective evaluation method, primary tast performance method,secondary task performance method and physiological measures were collected and screened by test of significance to build the model. The feasibility of the model was checked in fighter C simulator by test pilots. Results Five out of 7 indexes, including Cooper Harber subjective ratings, P300 latent time, mental workload reserve, flight parameters maintaining rate and information processing speed were admitted and weighted to build the model. The result of evaluation of mental workload in fighter C simulator with this model was consistent with the result evaluated subjectively by test pilots. Conclusion This model for assessment of mental workload is reliable and easy to operate.
