Cognitive Ergonomics Applied to the eQRH: Developing an Electronic Quick Reaction Handbook for Use During Aviation Emergencies

Technology has transformed much with regard to in-flight use of electronic flight bags (EFBs), but little formal literature addresses guidelines for electronic (non-print) presentations designed to aid in "quick reaction" situations such as emergencies or abnormal conditions in flight. This paper contributes to the body of knowledge by describing the development of an electronic "Quick Reaction Handbook" (eQRH) using content from an aviation platform (the KC-135 aircraft). We describe design features that consider (1) technology capabilities and limitations, (2) the operational environment, and (3) human capabilities and limitations in stressful situations. We discuss specifically tailored cognitive engineering/cognitive ergonomics methods for overcoming challenges during development (such as translation of content from paper-based media, subject matter expert knowledge elicitation, and eQRH verification and validation). We describe generalizable cognitive ergonomics design principles for the eQRH, and formulate a procedural template (process model) and technical data "content templates" for general eQRH development.
