A chilled air plenum system for aircraft galleys adapted to be connected to a food cart bay for a food cart includes an air return plenum having a return airflow duct with a plurality of midline primary apertures and a plurality of secondary lateral side edge apertures for receiving return airflow from the food cart. The return airflow duct also includes a central lower resilient back stop and lateral side edge resilient back stops to prevent a cart from impacting the rear of the food cart bay. The return air plenum cab be at least partially integrated into a galley back wall structure.

The chilled air plenum system for aircraft galleys of claim 11, wherein said plurality of primary apertures comprises an upper midline primary aperture, an intermediate midline primary aperture, and a lower midline primary aperture, all centrally located along the midline of the return airflow duct. 13. The chilled air plenum system for aircraft galleys of claim 11, wherein said plurality of secondary apertures comprises a plurality of upper lateral side edge secondary apertures, a plurality of intermediate lateral side edge secondary apertures, and a plurality of lower lateral side edge secondary apertures, all located along the lateral side edges of the return airflow duet. 14. The chilled air plenum system for aircraft galleys of claim 11, wherein said galley chiller air return plenum is configured to be removably connected to the rear portion of the chilled galley food cart bay. 15. The chilled air plenum system for aircraft galleys of claim 11, wherein said return airflow duct includes a return airflow duct adapter configured to be connected to the return airflow duct inlet to the chiller unit. 16. The chilled air plenum system for aircraft galleys of claim 11, wherein said return airflow duct includes a centrally mounted lower back stop located along the midline of the return airflow duct and a plurality of lateral side edge resilient back stops located along the lateral side edges of the return airflow duct and configured to prevent the aircraft galley food cart from impacting the rear portion of the galley food cart bay. 17. The chilled air plenum system for aircraft galleys of claim 16, wherein said centrally mounted lower back stop is mounted on a vacuum formed removable snorkel portion of the return airflow duct. 18.
