Abstract:

Previous research has shown that the presence of aircraft head-up display (HUD)

symbology indicating altitude improves maintenance of altitude, but at a cost

to (ground) path-following ability. We term this the altitude/path performance

trade-off. Differential motion between HUD symbology and the world has been

posited as leading to attentional tunneling on the symbology at the expense of

flight information in the world. In the first of two flight simulation studies,

scene-linked symbology was tested to see if the absence of differential motion

cues between the symbology and the world would negate attentional tunneling and

the resulting performance trade-off. This not only proved to be the case, but

relative to a control condition with no explicit altitude display, scene-linked

symbology yielded improved altitude and path performance. In the second study,

an attempt was made to discern the source of improvement in path performance

found with the use of scene-linked symbology. The result suggests that flight

task integration and fusion of the symbology with the world permits object-based

parallel processing benefits that are evidenced by improved path-following

performance. 5p.
