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

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.

An outward opening plug-type aircraft door of the type adapted to be mounted in an ingress/egress cutout opening formed in the aircraft fuselage and bounded by generally vertical fore and aft fuselage frame members, said door comprising, in combination: (a) means defining a generally L-shaped hinge element having a relatively short hinge arm and a relatively long hinge arm; (b) means for securing said relatively short hinge arm to one of the generally vertical fore and aft frame members bounding the ingress/egress cutout opening in the aircraft fuselage with freedom for rotation about a first generally vertical hinge axis; (c) an outwardly opening plug-type aircraft door dimensioned to be received in and to close the ingress/egress cutout opening in the aircraft fuselage, said door being mounted in cantilever fashion on the free extremity of said relatively long hinge arm for rotation about a second generally vertical hinge axis and with freedom for limited up and down vertical movement relative to said hinge element and the ingress/egress cutout opening in the aircraft fuselage; (d) means defining a programming mechanism interconnecting said aircraft door, said hinge element and said one of the fore and aft fuselage frame members for controlling the rotational attitude of said aircraft door as the latter is shifted between fully closed and fully opened positions and for maintaining said aircraft door in a plane essentially parallel to the plane containing the ingress/egress cutout opening at all door positions, said programming mechanism defining means comprising: (i) a first 4-bar linkage assembly defined by (1) said relatively short hinge arm; (2) bell crank defining means pivotally secured intermediate its opposite ends to said L-shaped hinge element at the juncture of said relatively short and said relatively long hinge arms; and (3), a first control link pivotally secured at one end thereof to one end of said bell crank defining means and pivotally secured at the opposite end thereof to said one of the generally vertical fore and aft frame members for rotation about a third generally vertical hinge axis parallel to and spaced from said first generally vertical hinge axis; and, (ii) a second 4-bar linkage assembly defined by (1) said relatively long hinge arm; (2) said bell crank defining means; and (3), a second control link pivotally secured at one end thereof to the other end of said bell crank defining means and pivotally secured at the opposite end thereof to said door for rotation about a fourth generally vertical hinge axis parallel to and spaced from said second generally vertical hinge axis; with said first and second 4-bar assemblies being interconnected to one another by said bell crank defining means and being arranged such that when said aircraft door is in the fully opened position the components defining said first 4-bar linkage assembly lie in an essentially vertical plane immediately adjacent said one of the generally vertical fore and aft frame members bounding the ingress/egress cutout opening in the aircraft fuselage, the components defining said second 4-bar linkage assembly lie wholly outside the aircraft fuselage and either fore or aft of the ingress/egress cutout opening, and the ingress/egress cutout opening is essentially devoid of any obstructions when said aircraft door is in the fully open position; (e) cooperable latch means mounted on the fore and aft vertical edges of said aircraft door and on the fore and aft generally vertical fuselage frame members bounding the ingress/egress cutout opening for selectively latching said aircraft door in a seated, fully closed and latched condition; and, (f) manually operable actuating means mounted on said aircraft door for lifting said aircraft door within the fuselage ingress/egress cutout opening a distance on the order of approximately two inches from a seated, fully latched and closed position to a raised unlatched and closed position and for lowering said aircraft door within the fuselage ingress/egress cutout opening a distance on the order of approximately two inches from a raised, unlatched and closed position to a seated, fully latched and closed position; whereby said aircraft door may be shifted between a seated, fully latched and closed position and a raised, unlatched and closed position by manual actuation of said actuating means; and, whereby said aircraft door, when in a raised, unlatched and closed position, can be manually shifted out of the ingress/egress cutout opening to a fully open position wherein said door is located outboard of the aircraft fuselage with the door\s inner surface and the fuselage outer surface in facing relation with said door being maintained in a plane essentially parallel to the plane containing the ingress/egress cutout opening at all door positions intermediate a fully closed and fully opened position and with the ingress/egress cutout opening being substantially devoid of laterally projecting hinge and/or actuating components when said door is fully opened.
