The girt connects the escape slide to the girt bar.
(2)
The girt bar is installed through the loop in the girt and attached to the floor fittings. The girt bar is locked and unlocked from the floor fittings with the mode selector lever.
E. Release System
(1) The escape system pack is automatically released when the door is opened from the inside in the ENGAGE mode. The lanyard attached to the girt bar releases the harness latch at the lower shelf. The lower shelf turns down to let the pack fall below the cover. The cover, which is hinged at the top, is pushed away from the door as the pack falls. The girt bar stays attached to the floor fittings and pulls on the girt to inflate the escape system.
F. Inflation System (Fig. 4)
(1)
The escape slide is automatically inflated when the pack is released. As the pack falls below the door, the inflation cable, which is connected to the inflation cylinder regulator, releases gas pressure from the inflation cylinder. Gas flows from the inflation cylinder, through hoses, to aspirators on the escape slide. The aspirators pull in ambient air to help inflate the escape slide, along with the gas from the inflation cylinder.
