Similarly, color helps information stand out and aids bottom-up processing, which starts when “environmental energy stimulates the receptors” (Goldstein, 2021). In other words, if “FIRE” is in bright red letters, we notice it! From a human cognition standpoint, research has revealed that color and patterns are a significant factor in a pilot’s ability to recognize an expected source of information. Symbols with a low contrast to surrounding or background colors result in a higher incidence of missed cues and increased recognition time when compared to similar symbology in high contrast. Similar research projects explored the importance of highlighting the border


around something that the pilot had set, such as a target altitude or a desired course. Augmented PFDs integrate bold, colored boxes around autopilot-controlled parameters such as airspeed, altitude, or localizer indications. “Based on the significant improvements of pilot’s situation awareness, visual scan pattern of attention distributions, and perceived mental workload, the


augmented visualization


PFD design proved more effective on human-computer interactions than the traditional PFD in the flight deck.” (Li et al., 2020). The research proves what pilots knew...it’s easier to quickly identify information when the manufacturer makes it easier to find!
