Abstract
To increase aviation maintenance and inspection safety, we propose a web-based training system (WBTS) for technician training and performing maintenance tasks. Toward this goal, the risks of human errors were considered for each procedure from the perspectives of performance shaping factors (PSFs). WBTS functions include English and Chinese explanations, human error effects on human-machine system, human errors relative to serious rankings and frequency, and graphic information aid in each component removal and installation procedure. To verify the proposed platform, experiments were conducted on a JT8D engine during the inaugural flight of Boeing’s 727 to compare traditional workcard and proposed WBTS in two complex teamwork tasks. The results revealed that teams’ risk cognition, situation awareness, and performance have been increased by proposed WBTS comparing to that by the traditional work-card instructions.KeywordsHuman errorperformance shaping factormaintenance incidentsWBTSsituation awarenessworkload
