Study on fatigue of pilots during simulated flight training based on electroencephalogram

Objective: To study EEG during simulated flight training,then to explore the situational character of mental fatigue of the pilots.Methods: Fifty male pilots were randomly chosed to be recorded their EEG including rest,flight and recovery phase.Then the band waves of EEG were analysed among the three phase.Results: ①During flight,the amplitude of α、β、SMR、θ、γwaves tended to increase.These changes seemed obviously in SMR、θwaves.②After flight,all the amplitude of the waves declined except for β wave of the right lobe,and most of them were still higher than those before flight(P0.05);③The right brain showed a higher cerebration than the left,especially in θ wave.Couclusion: Mental fatigue is started during the flight training,and the right lobe has a severe mental fatigue than the left.After flight,mental fatigue showes a slow recovery.
