Human-rating Design of Visual Coding Based on the Airworthiness Requirements

China is carrying out the development of civil aviation aircraft which contains over 150 seats and will be flight-tested in 2014. Aiming at the visual coding design of the integrated display system for aircraft cockpit, it is considered that the human-rating design of visual coding has a direct effect on the ergonomics and safety of the pilot operating an aircraft. Therefore, this study focuses on the human-rating design of visual coding based on the airworthiness requirements, including the interpretation and analysis of the ergonomics airworthiness requirements, the ergonomics design of character size and color matching of visual coding. Drawn by the study: European and American airworthiness regulations have the same basic requirements but stronger operability compared with Chinese ones; the ergonomics design method of visual coding proposed in the current study is feasible, and the experiment results of the character size and color matching are consistent with the regulations published by the European and American airworthiness authorities, which can be applied to the development of China's airworthiness regulations.
