Abstract: A mobile platform galley cart storage and retrieval system includes a plurality of joined walls defining a galley area. A plurality of mobile carts are stored in the galley area, including at least a first side-by-side subgroup of carts and a second-side-by-side subgroup-of carts positioned above the first subgroup. An optional third subgroup is positioned above the second subgroup. An automatic transfer system lifts and horizontally transfers carts to predetermined storage locations on racks supporting each elevated subgroup of carts. The carts are stored in either randomly accessible locations or in first-in/last-out locations.
