Pilot Performance Using Head-up and Head-down Synthetic-Vision Displays for SA CAT I Approaches

摘要

Thirteen two-person crews flew 39 approaches each to runway 34R at Seattle-Tacoma airport in a 737-800level D flight simulator using both head-up and head-down synthetic-vision displays. The within-subjectdesign manipulated display type, runway-lighting configuration, ambient illumination, and two combinationsof decision height and runway visual range associated with Special Authorization Category I and IIapproaches. Data collected/analyzed included training trials, instrument landing system tracking, touchdownpoint and vertical velocity at touchdown, and pilot opinions on the adequacy of the display formatsfor the specific task. Results indicated that there was a small but reliable difference in touchdown pointbetween day and night approaches (longer in day) and that distance from centerline was also slightly affectedby display type. Mean vertical velocity at touchdown was also affected slightly. Data indicated thatthere appeared to be no operationally significant differences as a function of display type or other variablesexamined.
