Objective Through the establishment of the model of mental fatigue which was induced by continuous mental workload, compare the changes in cognitive function before and after simulated flight and investigate the pattern of heart rate variability (HRV) during the period of simulated flight, thus providing the foundation of screening objective indices for monitoring mental fatigue. Methods A total of 30 participants were informed to take part in a simulated flight for 4 hours. They were arranged to complete the Stanford Sleepiness Scale (SSS) and two cognitive tests, including psychomotor vigilance task (PVT) and shifting attention test (SAT) before and after simulated flight severally. HRV was recorded continuously during the period of simulated flight. Results After simulated flight, the scores of SSS significantly increased (P
