Research on the Index System for Evaluating the Ergonomics Design of Helicopter Cockpits

Helicopter cockpit ergonomic evaluation is a process of judging whether the matching relationship design of pilot-related displays, controllers and auxiliary components in cockpit design meets ergonomic requirements based on helicopter cockpit design specifications and pilots' operating experience. Based on the analysis and trade-off study of the influencing factors of helicopter ergonomics, combined with the design features of the cockpit and the pilot's operating procedures, this paper initially establishes an index system for evaluating the ergonomics. The index system for evaluating the ergonomics was screened and optimized according to the results of expert consultation. Finally, 3 first-level evaluation objectives, 9 second-level evaluation objectives, 23 third-level evaluation objectives, and 78 evaluation indexes were obtained. The evaluation methods and evaluation rules of the indexes have formed a scientific and reasonable index system for evaluating the ergonomics of helicopter cockpits. It lays a foundation for the comprehensive evaluation of helicopter cockpit ergonomics with multiple indexes.
