In complex combat environments,pilots need to quickly and accurately acquire and process a large amount of information.The rationality of the design of the cockpit display and control interface directly determines the pilots work efficiency and decision-making quality.From the perspective of human-machine ergonomics,this paper systematically analyzes the design elements and principle requirements of the human-machine interaction interface for military aircraft cockpit display and control,and elaborates on how to incorporate these principle requirements into the design process to guide the application of human-machine ergonomics in the top-level design of aircraft cockpit display and control systems.
