Abstract: A passenger cabin for a vehicle has an upper passenger deck with an upper arrangement of seats, a lower passenger deck with a lower arrangement of seats, an upper floor for the upper passenger deck arranged between the upper passenger deck and the lower passenger deck, and a lower floor for the lower passenger deck delimiting the lower passenger deck. The upper floor has a central hump region extending along a longitudinal axis of the passenger cabin at least in regions and above which the upper arrangement of seats is arranged, and two side regions adjacent to the hump region. The central hump region is raised relative to the side regions. The lower floor has a lower gangway, wherein the at least one lower arrangement of seats is arranged below the side regions of the upper floor, and the lower gangway is arranged below the central hump region.

Abstract: A double-deck airplane that facilitates passenger embarking/disembarking and cargo loading/unloading operations in order to maximize the number of flight missions carried out in a given time. The floors of its upper and lower decks are planar surfaces extending continuously inside the fuselage in at least the inner space of the fuselage intended for the payload; the lower deck is located at a height from the ground that allows carrying out passenger embarking/disembarking via equipment incorporated in the airplane without any external airport ground equipment; passenger and/or cargo compartments are distributed on the upper and/or lower decks; and the lifting structure is disposed in the airplane in a manner that none of its components crosses the upper and lower decks.

Abstract: The invention provides a double-deck airplane that facilitates passenger embarking/disembarking and cargo loading/unloading operations in order to maximize the number of flight missions carried out in a given time. Among other the airplane has the following features: the floors of the upper and lower decks (41, 43) are planar surfaces extending continuously inside the fuselage in at least the inner space of the fuselage intended for the payload; the lower deck (43) is located at a height from the ground that allows carrying out passenger embarking/disembarking autonomously without any specific airport ground equipment; passenger and/or cargo compartments (64, 63) are distributed throughout the upper and/or lower decks (41, 43); the lifting structure is disposed in the airplane in a manner that none of its components crosses the upper and lower decks (41, 43).
