Head-up displays (HUD) assist pilots, especially in theapproach and landing phase. In this paper we compared pilots’eye-tracking behavior between a pathway-in-the-sky layout versus the moreconventional two-dimensional symbology in an HUD in a fixed-based cockpitsimulator. In particular, we wanted to assess how visual attention wasdistributed within each layout (tunnel and standard). Performance andeye-tracking data were recorded, as well as workload and situation awarenessmeasures. Results showed that the tunnel-in-the-sky symbology provided a veryhigh tracking performance with low perceived workload and high perceivedsituational awareness. The analysis of the eye-tracking data revealed possibleattentional tunneling with the tunnel-in-the-sky symbology and large differencesbetween the displays in the distribution of visual attention.
