The purpose of this study was first to determine the effect of acceleration on a pilots ability to actuate the ejection controls of two makes of ejection seats, the McDonnell-Stanley seat equipped with an experimental torso-head restraint system and the Martin-Baker G-5 seat with the integrated harness restraint system. It was also an objective of the study to determine the degree to which the Mark V exposure flight suit and Mark IV Goodrich and the AX-83 Arrowhead lightweight full pressure flight suit impeded a pilot in the actuation of the ejection controls when compared to his performance while wearing the summer flight suit. The results indicate that a pilot, under conditions of acceleration may not be able to reach either the face curtain or the D-ring. Any encumbrances such as an exposure suit or a full pressure suit will decrease the probability of his successful ejection. Failure of the canopy to jettison upon operation of ejection control and the subsequent requirement for use of the emergency actuation control will further decrease this probability if he is wearing an inflated full pressure suit.
