24、 3.6 Design and construction. The RSSK shall be designed and oriented in such a manner as to accommodate and provide a maximum of comfort, convenience, and freedom from hazard for the aircrewman (lower limit 3 percentile man, upperlimit 98 percentile man, as specified in ACEL Report No. 533). The se

25、at kit shall be designed or oriented in such a manner as to integrate satisfactorily with the airframe, seat, and aircrew- mans personnal equipment. The seat kit shall be designed to accommodate an emergency bailout oxygen system and applicable survival equipment within the configuration envelope. T

26、he seat kit shall be designed such that any hardware, handles, or other equipment protruding above the seat kit shall not cause pressure points or discomfort during service usage, ejection, or possible crash loads. The container shall provide attachment to the aircrew- mans torso harness such that i

27、t will stay with the aircrewman during ejection and fall. The seat kit when installed in the seat shall be compat- ible with the in-service adjustment of the seat and maintain the in-service pilots eye reference level requirement and accommodate the 3 to 98 per- centile aircrewman. As a design goal,

28、 in aircraft where the in-service adjustment of the ejection seat is physically limited by the anthropometry of the 3 or 98 percentile aercrewman, the design of the seat kit shall compensate, where possible, the adjustment limitations on the ejection seat to allow for full-up and full-down adjustmen
