Establishment and Verification of Flight Fatigue Model Induced by Simulated Aircraft Driving

On the basis of work analysis for airline pilot, joystick operating and instruments monitoring are extracted as the two core tasks, to build a simulation of the aircraft driving induced flight fatigue model. The model including the computerized simulation of dual task operation module, system management module and eye video monitoring module. In the validation study, 15 volunteers were recruited, their scores on the Stanford sleepiness scale (SSS) and their percentage of eyelid closure (PERCLOSE) in the task was recorded for 5 min were collected before and after the fatigue induced task for 3 h. The validity of the model was verified by comparing the subjective and objective fatigue indexes before and after the fatigue induced task. the score of SSS was increased, and the fatigue closure time of eyelid closure was significantly prolonged, all reaching the statistically significant level (P < 0.01). The simulation of aircraft dual task model can effectively induce flight fatigue and provide a tool for flight fatigue research.
