Abstract
The Peripheral Vision Horizon Display (PVHD) is an expanded artificial horizon line which is produced by sweeping the beam of a red laser across the instrument panel in front of the pilot. The PVHD is intended to provide the pilot with visual orientation information through peripheral vision without the need to look directly at the display. The potential advantage is a reduction in the requirement to constantly refer to the attitude indicator (AI) in order to maintain awareness of orientation when visual orientation cues from outside the cockpit are not available. Consequently, it is hypothesized that both the visual workload associated with scanning the AI in critical situations, and the likelihood of a loss of visual orientation, are reduced. The present study examined the effect of the PVHD on the instrument scanning behavior of pilots during two types of instrument approaches. TRUNCATED
