Abstract
Two anthropometric accommodation studies were conducted in response to ta taks from DTA-6. The first study examined the effect of three parachute packs (Tutor, T-Bird and CF-5) on seated position, or more specifically knee position, inside the cockpit. The second study concentrated on parachute harness fit issues with respect to accommodation of males and females. Twenty males and seven females were selected to participate in the experiments. Subjects wore each of three parachutes (Tutor, T-Bird and CF-5) in summer and winter clothing conditions. Knee position relative to Tutor and T-Bird seats were measured for each test condition. In the T-Bird seat, the results showed that the larger parachute size (CF-5) would move pilots' knees forward by 1.0-cm on average, compared to the T-Bird parachute. It is anticipated that this increase would be sufficient to affect approximately 10% of T-Bird pilots who would have to be screened out to meet current ejection clearance standards. Parachute harness fit was assessed in two ways: objectively, by measurement of excess strap length remaining after adjustment, and subjectively, through an overall assessment performed by DCIEM Aviation Technicians.
