ABSTRACT

Engine failure events during critical phases of flight are a rare yet very real possibility on commercial aircraft. The response of the pilots to these events is vital to minimizing possible adversity. New technologies are in development that provide enhanced information on the status of the aircraft engine after sustaining engine damage in order to guide pilot’s decision making. It is important that this enhanced information is aligned with the requirements of the user. This paper describes how user input can effectively be incorporated early on in the design process of new technologies to understand how current systems may be improved. The Perceptual Cycle Model (PCM) is applied to in-depth interview reports from commercial airline pilots on their responses to different engine failure events caused by bird-strikes to the engine. Application of the PCM demonstrates where current processes may be better supported to enhance pilot decision making from such events. From this, areas where improvements could be made using future avionic systems are presented, with user-led design recommendations.

摘要

在关键飞行阶段，发动机故障事件在商用飞机上是一种罕见但非常真实的可能性。飞行员对这些事件的反应对于最大程度地减少逆境至关重要。正在开发新技术，这些技术在遭受发动机损坏后可提供有关飞机发动机状态的增强信息，以指导飞行员的决策。重要的是，此增强的信息必须与用户的要求保持一致。本文介绍了如何在新技术的设计过程中及早有效地合并用户输入，以了解如何改进当前系统。感知周期模型（PCM）应用于商业航空公司飞行员对因鸟击而引起的各种发动机故障事件的响应的深入采访报告。PCM的应用表明，可以更好地支持当前流程以增强此类事件的飞行员决策能力。由此，提出了可以使用未来的航空电子系统进行改进的领域，并提出了用户主导的设计建议。
