Abstract
An inward/outward movable plug-type aircraft passenger door (50) including: (i) a hinge assembly (56) and programming control mechanism (100, 114, 116 and 105, 114, 119) therefor; (ii) a latch/unlatch mechanism (58, 70, 82, 88, 89, 90, 91, 92, 94 and 95) therefor; (iii) a pressure lock gate (69) and actuating mechanism (58, 75, 76, 78, 79, 80, 81, 82 and 84) therefor; and (iv), a deployable emergency evacuation system (59) and actuating linkage (60, 132, 134, 135, 136, 138, 139, 140, 141, 142 and 144); wherein the aircraft door (50) is of the type adapted to be translated between a first fully closed and latched position and a second fully opened position while being maintained essentially parallel to the plane containing the ingress/egress cutout opening (51) in the fuselage (52) at all intermediate door positions--i.e., the aircraft door (51) is not pivoted or rotated about the hinge axis (104 and/or 109) to, in effect, turn the door (51) inside-out, but, rather, is moved with translatory motion outward of the ingress/egress cutout opening (51) in the fuselage (52) to a fully open position where the door's inner skin (66) is in facing relation to the fuselage (52) outer skin.
