To predict the risk of fatigue for flight crews on international flights under the new operating model policy of the civil aviation exemption approach policy during the COVID-19 outbreak, and to provide scientific validation methods and ideas for the exemption approach policy. This paper uses the change in flight crew alertness as a validation indicator, and then constructs an alertness assessment model to predict flight crew fatigue risk based on the SAFTE model theory. Then, the corresponding in-flight rotation plans for the flight is designed according to the exemption approach policy issued by the CAAC, the CCAR-121 part policy and the real operational requirements of the airline, respectively, and finally the simulation results is compared by comparing the pilot alertness and cockpit crew alertness under the exemption approach policy and the CCAR-121 part policy with the flight duration. The results show that the flight crew alertness level for the flight in-flight rotation plan simulation designed under the exemption approach policy is higher or closer to the pilot alertness level for operational flights under the CCAR-121 Part policy. This validates the reasonableness and safety of the exemption approach policy issued by the CAAC to meet the requirements of epidemic prevention and control, and provides scientific support and solutions for fatigue monitoring and management.
为了预测 COVID-19 疫情期间，按照民航豁免政策的新运行模式政策，国际航班机组人员的疲劳风险，并为豁免政策提供科学验证方法和思路。本文以飞行机组警觉性变化作为验证指标，然后基于 SAFTE 模型理论构建警觉性评估模型，预测飞行机组疲劳风险。接着，根据中国民航局发布的豁免政策、CCAR-121 部政策以及航空公司的实际运行需求，分别为航班设计相应的豁免政策下的飞行中轮班计划，最后通过比较豁免政策和 CCAR-121 部政策下的飞行持续时间与飞行员警觉性和驾驶舱机组警觉性，对模拟结果进行比较。结果表明，豁免政策下设计的飞行中轮班计划模拟的飞行机组警觉性水平更高或更接近 CCAR-121 部政策下的运营航班的飞行员警觉性水平。这验证了中国民航局发布的豁免政策的合理性和安全性，满足了疫情防控的要求，并为疲劳监测和管理提供了科学支持和解决方案。
