Abstract: A supply system for passenger aircraft uses one or more catering containers which are loaded with the aid of the aircraft's loading system into the cargo hold of the passenger aircraft and positioned in vertical alignment with a supply distribution and work cabin on the passenger deck or floor of the aircraft. A horizontal conveying system is capable of moving transport carts or standardized packages in the directions of a rectangular coordinate system for bringing carts or packages into a lifting position. A vertical lift cooperates with the horizontal conveyor system for bringing trolleys initially held in the carts or standardized packages into the distribution and work cabin. Instead of equipping the catering container with a horizontal conveyor system that works in the X- and Y-direction, it is possible to use any other robot system for retrieving standardized packages and/or trolleys from the catering container.
