Evaluation of Pilot Mental Workload for Simulator Based Training Using Heart Rate Variability

The purpose of this study is evaluation of mental workload when pilot trainee practices of maneuvering simulator and evaluation of validity of it as substitution for real ship from its tendency. The subjects had trained for three months who were equipped heart rate monitor. I calculated LF/HF to process the heartbeat interval data using spline interpolation and MEM (maximum entropy method) and defined result data as mental workload. In addition, I set the ordinal reference value and evaluated reaction above this numerical value. I summarized the number of times that mental workload and grouped for mental workload tendency to compare for the contents of the corresponding scenario of simulator. In consequence, I analyzed their timing of mental workload and poor contents. As a result, reactions were differ from each them and had no uniformity for the timing or contents. Additionally in paradoxical, we understood that it is possible to get mental tendency for each to do simulator practice.
