Human-Machine Ergonomics Analysis of Civil Aircraft Electric Pilot Seats

This paper uses a structured evaluation framework to study the ergonomics of electric pilot seats in modern civil aircraft. We have established a multi-level indicator system to examine the adjustability, pressure distribution, dynamic response and, fatigue relief effect of the seat. All experimental data were obtained from a full-scale cockpit simulator environment, where a ground-based mock-up and motion-free simulated cockpit were used to replicate real operational posture, control-reach conditions, and long-duration mission loads. This framework combines experimental measurement and fuzzy evaluation techniques to quantify the quality of human-computer interaction. Test results show that compared with ordinary seats, the prototype seat has a wider adjustment range, a more uniform pressure distribution, and a smoother dynamic response. It is particularly worth mentioning that it can delay the emergence of fatigue during long-term operation, which proves the advantages of the electric adjustment mechanism. The simulated-cockpit test conditions ensure that these results are reproducible and representative of actual cockpit usage scenarios. This findings not only provide theoretical guidance and engineering basis for optimizing the cockpit seat system, but also provide methodological reference for applying fuzzy analysis in aerospace ergonomics research.
