Traffic and Flight Guidance Depiction on a Synthetic Vision System Display: The Effects of Clutter on Performance and Visual Attention Allocation Technical rept

摘要

Fourteen pilots flew a synthetic vision system (SVS) display through a terrain and traffic-rich environment in a high fidelity flight simulator. Traffic information was hosted on the SVS display. In a 2x2 factorial design, the SVS display hosted a highway-in-the-sky in half the conditions, while instrument panel information and a flight path velocity vector was the sole means for guidance in the other conditions. In half the trials the instrument panel overlaid the SVS display, and in the other half it was separate, allowing us to examine the effects of the resulting clutter. Tunnel guidance, and clutter effects were examined as they influenced routine flight performance, SVS traffic detection and change awareness, and the pilots response to offnormal events, as these were mediated by visual scanning measures of attention allocation.
