Drop down overhead galley stowage system

A method of installing an aircraft overhead stowage system for a cross-aisle galley complex, the method comprising:

• installing a plurality of bin support rail fittings onto a plurality of bin support rails disposed above a ceiling of a cross-aisle galley complex;
• positioning a stowage compartment housing supported by a stowage support structure above the ceiling of the galley complex, the stowage compartment housing including a first stowage compartment and a second stowage compartment each movably engaged with and disposed inside the stowage compartment housing, each stowage compartment movable between a stowed position and a deployed position relative to the stowage compartment housing;
• aligning the stowage compartment housing and the stowage support structure with the bin support rails;
• fastening the stowage support structure to the bin support rails using the bin support rail fittings such that the stowage compartment housing is structurally supported above the ceiling of the galley complex;
• installing a control panel in a selected location accessible to a cabin crew member and electrically connecting the control pan& to a vacuum system mounted on the stowage compartment housing, wherein the control panel is configured to activate the vacuum system to move one of the first stowage compartment and the second stowage compartment between the stowed position and the deployed position;
• and
• installing a galley ceiling system on the ceiling of the galley complex, comprising:
• installing a first ceiling panel on the ceiling of the galley complex below the stowage compartment housing, the first ceiling panel including attached ceiling-mounted flex hoses for connecting to a ventilation duct and to an air passageway disposed above the ceiling of the galley complex;
• attaching aircraft side systems interfaces to a center ceiling systems panel the aircraft side systems interfaces including a vent plenum, a gasper nozzle, and emergency lighting;
• installing the center ceiling systems panel with attached aircraft side systems interfaces into the ceiling of the galley complex below the stowage compartment housing and adjacent to the first ceiling panel;
• and
• installing a second ceiling panel on the ceiling of the galley complex below the stowage compartment housing and adjacent to the center ceiling systems panel opposite the first ceiling panel.
