ABSTRACT:
In a door system for a passenger aircraft, a door panel is mounted on an aircraft structure so that it can pivot around at least one pivot axis and the door panel is movably guided at the end of the inward pivoting movement on a lifting movement path that runs essentially in conformance with the aircraft outside contour and runs transversely to the pivoting direction. Interengaging elements on the door frame and door panel are engaged in the completely closed position, moved out of shapewise engagement in an opposite lifting direction at the beginning of the opening process. The lifting movement takes place in a manner which is favorable for installation and is not prone to problems, while retaining an essentially horizontal pivoting movement path relative to the aircraft structure in such fashion that the pivot axis of the door panel is supported on the door frame with tilting position control and at the end of opening lifting movement, moves into essentially vertical alignment relative to the door frame. A door panel locking system is provided which is operated in the closed position of the door panel and, in a non-liftable manner, locks the door panel to the door frame independently of the swivelling and carrying device and of the tilting position control.
