Figure 6-18.—Survival kit and parachute removed.emergency code card, water storage bag, a 50-footnylon cord, and shark repellent.OperationAs the seat moves up the guide rails duringseat ejection, the aircraft-attached emergencyoxygen lanyard is pulled automatically to actuatea supply of emergency oxygen. In the event ofhigh-altitude ejection, the emergency oxygenprovides protection against blackout while thecrew member is descending to a safe altitude. Bypulling the manual kit-release handle on the rightside of the kit, the crew member may deploy thekit during parachute descent. Upon deploymentof the kit, the top and bottom halves separate;both halves are still connected to the crewmember by a retaining lanyard. The survivalkit gear remains with the bottom half of thecontainer (stowed in a zippered bag), while the liferaft separates from the container. A self-containedpneumatic bottle automatically inflates the liferaft, which remains attached to the crew memberby means of the retaining lanyard.Parachute deployment occurs following thecrew member/seat separation phase of normalseat ejection. If the crew member is above a presetpressure altitude of 14,000 (± 500) feet, an aneroidin the parachute barometric actuator delaysparachute deployment until the crew member hasdescended to the correct pressure altitude. Theparachute actuator delay cartridge then fires,causing parachute deployment. The parachutealso can be deployed manually by pulling aconventional D-ring rip cord.CARTRIDGES AND CARTRIDGE-ACTUATED DEVICES (CADs)The types of explosive devices incorporatedin egress systems are varied. The AME workingwith these devices must know how they function,their characteristics, how to identify them, their6-23
