Evaluation of Fatigue Induced During the Flight Tasks

摘要

The fatigue of the pilots in the flight tasks affects his cognition of flight data and the ability to operate the aircraft correctly. Due to the increasing number of daily flights, the probability of fatigue flying becomes higher, which is harmful to flight safety. Therefore, the research on how to detect pilot's fatigue during flight tasks is of great significance to ensure the safety of aviation. A simulation study with 11 groups of pilots was conducted to examine the correspondence between pilot's fatigue and their physiology data when they performed normal pilot flight training tasks. Result show that as fatigue accumulates, the participants' pupil diameter, heart rate, and duration of fixation on the area of interest are significantly different from the beginning of the experiment, we also proposed a comprehensive indicator to reflect the pilots' fatigue through polynomial analysis of these changing physiology parameter.
