A Study on the Helicopter Pilot’s Psychological and Physiological Influences by ‘Surprise and Startle Effect’

Surprise and Startle are often cited as potential or contributing factors in the cause of aircraft accidents because they can negatively affect pilots' situational awareness and decision-making.Accordingly, it is necessary to more clearly understand the effect on flight safety through the psychological and physiological reactions that occur to the pilots.Therefore, this study empirically analyzed the effects of Surprise and Startle on the pilot's psychological and physiological responses using a helicopter flight training device for the first time in Korea.As a result of the analysis, the ratio of recognition of Startle and Surprise, heart rate, and respiration rate showed a high difference between private pilots and commercial pilots.This is analyzed as the difference between long-term flight experience and flight time.In addition to presenting effective information for improving the education and training field of helicopter pilots in the future, it is intended to provide basic data for related research.
