An aircraft cabin air distribution system has a number of upper branch ducts 52 and lower branch ducts 54 feeding air from a supply duct 30 to respective upper and lower outlets 62,64 in the fuselage cabin. The upper outlets positioned higher, and the lower outlets positioned lower, than the supply duct. Preferably each upper branch is arranged opposite a lower branch, the branches meeting the supply duct at an 90° angle. The cabin may have overhead bins (fig.2,16) with the upper and lower outlets positioned at higher and lower levels than the bins, respectively. There may be a second supply duct (fig.2,30c) with further branches and outlets. The supply ducts preferably extend along the length of the fuselage, each duct either distributing air on a respective port and starboard side of the fuselage, or on the same side of the fuselage. A number of riser ducts (fig.2,32) may feed air from an air supply unit (fig.2,24), located in an unpressurised part (fig.2,11) of the fuselage under a floor of the cabin (fig.2,12), to the supply ducts. The air supply unit may include a mixer, receiving air from a number of sources.
