A Human Factors Validation Methods Incorporating the Degrees of Novelty, Complexity, and Integration of Cockpit Design Items

This paper introduces a comprehensive Human Factors validation framework for CS25.1302 regulation, explaining how the degrees of novelty, complexity, and integration impact the level of scrutiny required for aircraft cockpit design items. The background underscores the role of human factors consideration for new, complex, and integrated designs in aircraft cockpit. The study aims to provide designers and regulatory authorities with a systematic methodology for determining appropriate means of compliance tailored to the varying degrees of novelty, complexity, and integration of design items. This method outlines the process of selecting a reference aircraft, participants, criteria employed, and how to carry out the assessment. Furthermore, it proposes the framework for selecting appropriate means of compliance considering the level of scrutiny supported by a case study. This framework not only optimizes the Human Factors evaluation procedures but also develops more reasonable scrutiny strategies. This, in turn, contributes to the overall enhancement of cockpit design safety and reliability.
