Research on the Comprehensive Evaluation Method of Pilot Workload During Flight Test

High pilot workload during flight test may cause human error, which influences the safety of flight test. Currently, there are a few studies on pilots’ workload evaluation during flight test. The paper firstly analyzed the influencing factors of pilot workload during flight test and established the evaluation index system. Then, a comprehensive evaluation method of pilot workload during flight test combining improved Analytical Hierarchy Process method and fuzzy evaluation was proposed, and the fuzziness of pilot workload evaluation is fully considered. And then the factors of pilot workload affecting greater were analyzed and recognized quantitatively, and the suggestions for aircraft equipment improvement and pilot’s operation were put forward. At last, the model was used in the landing stage of a mission scenario in which a civil aircraft’s engine fails after flying over V1 and the validity of the proposed method is verified.
