Abstract: An aircraft incorporates a lift system for guiding a lift cabin. The lift cabin 21 is capable of servicing several decks in the aircraft. A guiding structure is mounted inside the aircraft fuselage 1 by mounting it to the floor and deck structures, while allowing for strains between the floor and the deck in the vertical direction. The lift cabin is capable of travelling down to the ground if a door in the underside of the fuselage is provided. The lift cabin is arranged on the guiding structure using a bogie truck mounted on the lift cabin, and the bogie truck may be actively connected with profile rails of the guiding structure via roll blocks. The part of the bogie truck carrying the roll blocks or other guiding element may remain within the fuselage, when the cabin is positioned on the ground.
