1. An articulated hinge assembly for connecting a door to a fuselage of an aircraft, the articulated hinge assembly comprising:
an articulated hinge arm having a first hinge member and a second hinge member pivotably coupled to the first hinge member at an elbow, the first hinge member including a fuselage fitting configured to be pivotably coupled to a fuselage bracket mounted to the fuselage adjacent a door opening of the aircraft, the second hinge member including a door fitting configured to be pivotably coupled to a door bracket of the door; and
a linkage assembly coupled to the articulated hinge arm, the fuselage fitting and the door fitting, the linkage assembly including a hinge linkage assembly coupled to the articulated hinge arm and the fuselage fitting, the hinge linkage assembly controlling movement of the first hinge member and the second hinge member relative to each other and relative to the fuselage fitting, the linkage assembly including a door linkage assembly coupled to the articulated hinge arm and the door to control positioning of the door relative to the second hinge member when the door is moved from a door closed position to a door open position, the linkage assembly configured to cause the door to move along a programed path relative to the fuselage as the door moves from the door closed position to the door open position.
