Effects of visual clutter on pilot workload, flight performance and gaze pattern

Visual clutter has received an increased interest by the aerospace community to characterize the negative impacts of information overload on pilots. Past studies found mixed effects of the primary flight display (PFD) visual clutter on flight performance. In this study, we created three experimental PFDs with different clutter levels (low, medium, high) and the same flight guidance function. Twelve pilots completed an instrument landing using all three PFDs. We found that pilots reported lower workload level (p
