An inflatable emergency evacuation slide system comprises a slide pack (60) with an emergency evacuation slide (10) stored in an uninflated, folded condition together with an inflator (30). A manual inflation lanyard (38) having a mechanical stop (44), such as a crimped ferrule located along its length, is routed in a conventional manner to a point proximal the girt bar (64) securing the evacuation slide (10) to the aircraft (20). The manual inflation lanyard (38) is routed through a grommet (46) at one end of an automatic inflation lanyard (50), the other end of which is attached to the aircraft exit door (18). In operation, when the aircraft exit door (18) is opened in the armed condition, the evacuation slide pack (60) is released from its storage compartment and is dropped from the emergency evacuation exit. As the free end (70) of the slide drops away from the emergency exit, the automatic inflation lanyard (50) reaches its limit of travel and the grommet (46) bears on the mechanical stop (44) located on the manual inflation lanyard (38). This action causes the manual inflation lanyard (38) to be withdrawn from the initiator (36) of the inflator (30) thereby beginning the inflation of the emergency evacuation slide (10).
