This study aims to investigate (1) the relationship between restricted sleep and Heightened Emotional Activity (HEA) during normal flight operations, and (2) whether sleep patterns influence the strength of the HEA as a response to threats. Accident investigation reports continue to highlight the relationship between restricted sleep and poor safety outcomes. However, to date we have a limited understanding of how sleep and HEA interact. A total of 302 sectors of normal airline flight operations were observed by trained observers, and instances of heightened emotional activity were recorded. During the cruise phase of each of these sectors, crew members were asked to calculate the amount of sleep they had obtained in previous 24 and 48 h. In the 302 sectors of normal flight operations, 535 instances of HEA were observed. Descriptive analyses of instances of HEA and sleep in the prior 24 and 48 h showed a significant relationship between the occurrence of HEA and recent sleep. The relationship between restricted sleep and HEA suggests that there may well be further implications with respect to operational safety.
(1) 在正常飞行作业中，睡眠受限与情绪高度活跃（HEA）之间的关系；(2) 睡眠模式是否会影响 HEA 对威胁的反应强度。事故调查报告继续强调了睡眠受限与安全结果不佳之间的关系。然而，迄今为止，我们对睡眠和 HEA 之间的相互作用知之甚少。通过训练有素的观察者观察了 302 个正常航空公司飞行作业的扇区，并记录了情绪高度活跃的情况。在这些扇区的巡航阶段，机组人员被要求计算他们在前 24 小时和 48 小时内获得的睡眠时间。在 302 个正常飞行作业扇区中，观察到 535 例 HEA。对前 24 小时和 48 小时内 HEA 和睡眠的实例进行描述性分析表明，HEA 的发生与近期睡眠之间存在显著关系。睡眠受限与 HEA 之间的关系表明，这可能对运营安全产生进一步影响。
