Abstract

This study analyzed performance correlates resulting from various applications of anthropometric data used in tactical aircraft cockpit design. Three anthropometric cockpit-geometry configurations were used as variables in performance testing a sample of 50 subjects, undergraduate and graduate college students as well as military pilots. The task was a simulated tactical, combat flight. Variables included: (a) viewing a display from a design eye-position based on uncorrected anthropometric data derived from traditional measuring techniques-erect, (b) viewing the display from the same position as (a) with the exception that supports were used to prevent or relieve fatigue-supported, and (c) viewing the display from a position 3.81-cm lower than the erect position to accommodate the postural displacement resulting from (i) normal upper body slouch, (ii) torso-restraint body retention, and (iii) wearing aviators equipment—actual. The mean performance scores in the actual condition were significantly better than scores which resulted from the supported or erect condition based on traditional application of anthropometric criterion.
