A hinge assembly for attaching a door structure to an aircraft fuselage is
provided. The door structure is linked to the aircraft body structure by
way of a programmable mechanical linkage that is attached to the hinge
member. The programmable mechanical linkage is actuated along the hinge
member so as to maintain the door structure attached thereto in a
controlled angular relationship relative to the longitudinal axis of the
aircraft fuselage through its attachment to the fixed aircraft frame.
