Abstract: Based on the study of visual area, main pathways of visual flow, ergonomics factors and the judgement of visual ergonomics, a synthetical evaluation of ergonomics study in visual information flow system of pilots has been built. Primary results reveal that there exists optimal, good and limit visual ergonomic area in the plane of pilots- visual area, and the vibrancy, dazzle, noises, shape, color, contrast, display mode play an important role in affecting visual ergonomics. During the process of airplay design, the information display area should lie in visual area of pilots. Its display layout and display mode should fall in line with visual ergonomics.
