A series of flight simulations was carried out to investigate the causal factors of attention capture, focusing on a traffic detection task while following a curved trajectory using a Tunnel-in-the-Sky display. The location (head-up or head-down) and size of the display were varied, and traffic detection time and path tracking performance were measured. The results show that the HUD gave the best path tracking at the expense of traffic detection performance, and supports the hypothesis that using a limited viewing volume and high display gain with a Tunnel-in-the-Sky display induces pilots to rely on precise guidance cues instead of the “tunnel” itself, consequently focusing much attention on the control task.
