The purpose of this evaluation was to quantify the effect of flight clothing and equipment on pilot accommodation in ejection seat tactical aircraft. The data derived from this evaluation are applicable to any similarly dressed and equipped aircrewman in tactical or training aircraft. Subjects selected for the study represented the typical range of aircrewmen body sizes within the Naval aviation population. Comparative anthropometric measurements were made between three conditions a unclad, b wearing summer flight gear, and c wearing winter flight gear. Volumetric quantifications of increased bulk, as well as angular quantifications of decreased mobility, were accomplished. The data describe significant limitations in cockpit reach capability and torso movement as a function of summer and winter flight clothing and equipment. The most restrictive item worn was the CWU-33P anti-exposure garment. An all-encompassing reengineering of the total system of flight clothing and equipment should be undertaken to lighten the weight and reduce the mobility-restricting bulk of such items. When designing crew station geometry and locations of controls and displays, designers should incorporate the maximum available data describing reduction in anthropometric mobility and increase in anthropometric volume, resulting from flight clothing and equipment worn on the body.
