Actuating mechanisms (106 and 122) for latching and unlatching an aircraft plug-type door (50) which is laterally and vertically translatable along tracks (55, 56 and 60) for movement into and out of an ingress/egress door opening (51) formed in the aircraft fuselage (52) and vertically along a path following the interior contour of the fuselage (52). The interior actuating mechanism (106) includes an interior door handle (99) mounted in the fuselage (52) adjacent the ingress/egress opening (51) and swingable between first and second positions, with the interior door handle (99) being operably associated with locking means (119, 120) for locking the door (50) upon closure thereof and for unlocking the door (50) preparatory to opening thereof. The external actuating mechanism (122) includes an exterior door handle (124) mounted in and flush with the fuselage (52) adjacent the ingress/egress opening (51) and swingable between first and second positions, with the exterior actuating mechanism (122) being normally disassociated with the interior actuating mechanism (106) so as to permit independent interior manipulation of the latter. Means (126, 134) are provided which are accessible only from the exterior of the aircraft for operatively associating the exterior door handle (124) with the interior door handle (99) and slaving the two together so as to permit door locking and unlocking from the exterior of the aircraft. The aircraft includes an emergency escape slide normally stowed within and carried by the door (50), and means (70, 75) for arming the emergency evacuation system to attach the escape slide to the passenger deck (74) and for disarming the system so that the escape slide is attached to the door (50). Locking means (89, 91, 94 and 95) are provided for releasably but positively locking the escape slide to the door (50) when the emergency evacuation system is disarmed. The door (50) may be opened from the interior of the aircraft with the emergency evacuation system armed or disarmed. Means (126, 141) are provided on the exterior of the aircraft for automatically disarming the emergency evacuation system preparatory to opening the door (50) from the exterior of the aircraft. |
