This study investigates military aircrews' ability to adapt to human-use centrifuge and determine what training items cognitively promote trainees' G tolerance to lower the G-induced loss of consciousness (G-LOC) incidence for the crews of high-performance combat aircraft. Questionnaires are used to assess the stressor for crews in taking centrifuge training and measure trainees' ability to adapt to the stress. Aircrews' stress caused by centrifuge training is decomposed into several constructs by factor analysis, and these constructs are used as the basis to implement stress management. The study results will improve the training quality by effectively measuring aircrews' ability to adapt to human-use centrifuge and analyzing the cognitive stressors of the trainees when taking the human-use centrifuge training to ensure flight safety.
