ABSTRACT

Objective

To illustrate how fatigue affects the workload, situation awareness, and control strategy of air traffic controllers.

Background

As air traffic control becomes more complex and demanding due to the increasing number of aircraft movements in major airport hubs, the need to particularly look into the interplay of performance shaping factors has also intensified. Despite the previous efforts of scholars to understand the framework of air traffic control based on factors on workload and situation awareness (SA) and its impact to shift in control strategy, the role of fatigue in such factors is ignored notwithstanding its relative impact on air traffic controllers as tasks are carried out in varying workload and work shift.

Methods

A case study is conducted in an actual tower control center in the Philippines to demonstrate the hypothesized relations among fatigue, workload, SA, and control strategy. Questionnaires based on SPAM, SASHA, Samn-Perelli fatigue scale, and visual attention self-report are deployed to measure air traffic controllers’ fatigue levels, SA, and control strategy.

Results

Fatigue has an inverse relationship with workload and has a significant effect on SA. Furthermore, fatigue is also found to have a significant relationship with some areas of interest including visual display terminal.

Conclusion

Such results underpin the resource allocation decisions of stakeholders in the commercial aviation industry geared toward fostering the welfare of air traffic controllers.

疲劳对空中交通管制员工作量、态势感知和控制策略的影响

摘要

客观的

说明疲劳如何影响空中交通管制员的工作量、态势感知和控制策略。

背景

由于主要机场枢纽中飞机起降次数的增加，空中交通管制变得更加复杂和要求更高，因此特别需要研究性能影响因素之间的相互作用也更加强烈。尽管此前学者们努力根据工作量和态势感知 (SA) 因素来理解空中交通管制框架及其对控制策略转变的影响，但尽管疲劳对空中交通的影响相对较大，但在这些因素中的作用却被忽略了控制器作为任务在不同的工作量和工作班次中执行。

方法

在菲律宾的一个实际塔台控制中心进行了案例研究，以证明疲劳、工作量、SA 和控制策略之间的假设关系。基于 SPAM、SASHA、Samn-Perelli 疲劳量表和视觉注意自我报告的问卷被用于测量空中交通管制员的疲劳水平、SA 和控制策略。

结果

疲劳与工作量成反比，对 SA 有显着影响。此外，还发现疲劳与包括视觉显示终端在内的一些感兴趣的领域有显着的关系。

结论

这些结果支持了商业航空业利益相关者的资源分配决策，旨在促进空中交通管制员的福利。
