Head-Up Display Standardization and the Utility of Analog Vertical VelocityInformation during Instrument Flight. (Reannouncement with New Availability Information)

摘要

The U.S. Air Force is attempting to create a standard symbol set for use with thehead-up display (HUD) as a primary flight reference. As part of that effort, 8 HUD-experienced pilots and 12 non-HUD-experienced pilots participated in a study that examined the effects of five different vertical velocity indicators in use under instrument flight conditions in a simulator. The five configurations assessed were (a) an altimeter arc, (b) a digital readout, (c) an altimeter arc with digital readout, (d) a dial, and (e) boxed digits with tape. The results clearly indicate that the altimeter arc with digital readout and the altimeter arc alone resulted in significantly more accurate maintenance of flight parameters (i.e., vertical velocity and altitude) than did the digital readout alone, the boxed digits with tape, or the dial. There were no performance differences due to prior HUD experience. Subjective data supported the objective findings in that pilots preferred either configuration that included the altimeter arc. These findings suggest that analog vertical velocity information is useful on the HUD, particularly when it is located in close proximity to the altimeter....
