The Effect of HUD (Head-Up-Display) Symbology Size on Operator Performance Under Various Luminance Conditions

Abstract

A study was conducted to determine the amount of reduction that could be imposed upon the size of symbology and scales used on the A-10 aircraft head-up-display (HUD). Four symbology and scale sizes were selected for study: 1) the current A-10 HUD display size; 2) a 15% reduction of the current display size; 3) a 30% reduction; and (4) a 45% reduction of the current display size. Twelve subjects 'flew' 15 two-minute, air-to-ground missions under three ambient background conditions -- 5 missions at 3000 foot-Lamberts (ft-l); 5 missions at 2000 ft-L; and 5 at 0.001 ft-L. During a given mission, the subject performed an information call out task (primary) and a compensatory tracking task (secondary) . Findings from this study indicate that within the range of symbology sizes used, no significant differences in performance were noted. Subjects responded rapidly and accurately, regardless of the symbology size used. Keywords: Attack bombers; Human factors engineering; Head-up display symbology; Operator performance; Luminance.
