ABSTRACT:
An emergency egress system (10) for facilitating emergency egress of passengers/crewmembers from an aircraft (4), which egress system (10) includes an egress panel (12), a panel frame (14) disposed about the egress panel (12) and a weather strip (16) defining back-to-back channels (18) for accepting the peripheral edges (12.sub.E, 14.sub.E) of the egress panel (12) and the panel frame (14). Furthermore, the emergency egress system (10) includes a plurality of retention devices (30) disposed about the periphery of the egress panel (12) for laterally retaining the egress panel (12) with respect to the panel frame (14) in a normal operating mode, a cam (80) operative to forcibly urge a portion of the weather strip (16) out of engagement with one of the peripheral edges (12.sub.E, 14.sub.E) and an actuation device (50) operative to sequentially disengage at least one of the retention devices (30) and actuate the cam (80) in an emergency operating mode. Following actuation, a passenger/crewmember may detach the egress panel (12) from the panel frame (14).
