Abstract The manipulation of colour in display symbology design has been recognised as a method to improve operator experience and performance. An earlier paper by the authors demonstrated that redundantly colour coding head-up flight symbology supported the manual flying performance of both professional and non-professional pilots during low-workload flying scenarios. In this study the workload and performance of 12 professional airline pilots was evaluated in high workload conditions whilst they flew manoeuvres and an instrument landing system (ILS) approach with and without the presence of colour feedback on a head up display (HUD). Workload was manipulated by presenting pilots with a concurrent auditory n-back task. Colour coded flight symbology reduced the subjective workload of the pilots during high workload conditions. In contrast, manual flying performance during high workload was not improved by the presence of colour coded feedback.

高工作负载飞行期间彩色编码平视飞行符号的工作负载优势

摘要 在显示符号系统设计中对颜色进行处理已被公认为提高操作员体验和性能的一种方法。作者较早的一篇论文表明，在低工作量飞行场景中，冗余颜色编码平视飞行符号支持专业和非专业飞行员的手动飞行性能。在这项研究中，12 名专业航空公司飞行员的工作负荷和表现在高工作负荷条件下进行了评估，他们在飞行机动和仪表着陆系统 (ILS) 进近时，在平视显示器 (HUD) 上是否存在颜色反馈。通过向飞行员展示并发的听觉 n-back 任务来操纵工作量。在高工作负荷条件下，彩色编码飞行符号减少了飞行员的主观工作负荷。相比之下，
