| 摘要： | This study investigated whether taxiway navigation is best supported by head-up or head-down presentation of either perspective (3-D conformal) or plan-view (2-D non-conformal) route guidance information. Thirty-two pilots taxied in low visibility conditions (300' RVR) in a high-fidelity simulator. Pilots were instructed to maximize speed while maintaining safe control of the aircraft as they taxied along a specified route. Pilots were randomly assigned to either the 2D or 3D display condition. Each subject completed half of the trials with the display in the head-up position, and half with the display in the head-down position. Expected events were presented in both near and far domains, while an unexpected event was presented in the far domain. Results revealed that, while pilots in both groups followed the cleared route with equal success, greater mean taxi speeds were supported by the 2D display, but lateral tracking error showed a slight advantage for the 3D display. A significant number of pilots using the 2D display failed to detect and respond to the unexpected far domain event (ground traffic), resulting in six collisions. The practical and theoretical implications of these results are discussed. |
