The effects of different display perspectives on pilot performance in weather and traffic avoidance tasks were evaluated using a 3 (display format: 2D toggle display, 3D toggle display and a 3D flexible display with a continuously manipulable viewpoint) x 2 (weather phenomena: convection and turbulence potential) within subject experiment. Results showed efficiency and situation awareness advantages when using a 2D toggle display. However, the 3D display with a continuously manipulable viewpoint performed similarly, and was superior to the 2D toggle display for safety. Additionally, different weather seemed to be best supported by different display formats and pilots were most conservative in convective weather conditions. This study provides guidance on ways to display weather and traffic information in order to support pilots’ safe navigation around weather hazards.
