Abstract: An aircraft reconfigurator system reconfigures a predetermined aircraft configuration, in particular a cabin layout, for which a distance between a position of a center of gravity of the aircraft, the center of gravity being optimized with respect to aerodynamic characteristics, and the actual position of the center of gravity is determined and thereupon an element of the aircraft is selectively displaced such that the position of the center of gravity is approximated to the optimized position of the center of gravity. Afterwards, a new aircraft configuration, in which the selected element is arranged in the new position, is determined. By means of the reconfiguration of the aircraft it is possible to save fuel.
