Background

Fatigue is pervasive, under-reported, and potentially deadly where flight operations are concerned. The aviation industry appears to lack a standardized, practical, and easily replicable protocol for fatigue risk assessment which can be consistently applied across operators.

Aim

Our paper sought to present a framework, supported by real-world data with subjective and objective parameters, to monitor aircrew fatigue and performance, and to determine the safe crew configuration for commercial airline operations.

Methods

Our protocol identified risk factors for fatigue-induced performance degradation as triggers for fatigue risk and performance assessment. Using both subjective and objective measurements of sleep, fatigue, and performance in the form of instruments such as the Karolinska Sleepiness Scale, Samn-Perelli Crew Status Check, Psychomotor Vigilance Task, sleep logs, and a wearable actigraph for sleep log correlation and sleep duration and quality charting, a workflow flagging fatigue-prone flight operations for risk mitigation was developed and trialed.

Results

In an operational study aimed at occupational assessment of fatigue and performance in airline pilots on a three-men crew versus a four-men crew for a long-haul flight, we affirmed the technical feasibility of our proposed framework and approach, the validity of the battery of assessment instruments, and the meaningful interpretation of fatigue and work performance indicators to enable the formulation of safe work recommendations.

Conclusion

A standardized occupational assessment protocol like ours is useful to achieve consistency and objectivity in the occupational assessment of fatigue and work performance.

空勤人员疲劳职业风险管理的数据驱动方法

背景

在涉及飞行操作的情况下，疲劳是普遍存在的、被低估的，并且可能是致命的。航空业似乎缺乏一个标准化、实用且易于复制的疲劳风险评估协议，该协议可在各运营商之间一致应用。

目标

我们的论文试图提出一个框架，该框架由具有主观和客观参数的真实数据支持，以监测机组人员的疲劳和表现，并确定商业航空公司运营的安全机组配置。

方法

我们的协议将疲劳引起的性能下降的风险因素确定为疲劳风险和性能评估的触发因素。以 Karolinska 嗜睡量表、Samn-Perelli Crew 状态检查、心理运动警戒任务、睡眠日志和可穿戴活动记录仪等仪器的形式对睡眠、疲劳和表现进行主观和客观测量，以获取睡眠日志相关性和睡眠持续时间和质量图表，开发并试用了一种工作流程，用于标记易疲劳的飞行操作以减轻风险。

结果

在一项旨在对三名机组人员与四名机组人员进行长途飞行的航空公司飞行员的疲劳和表现进行职业评估的运营研究中，我们肯定了我们提出的框架和方法的技术可行性，评估工具组，以及对疲劳和工作绩效指标的有意义的解释，以制定安全工作建议。

结论

像我们这样的标准化职业评估协议有助于在疲劳和工作绩效的职业评估中实现一致性和客观性。
