Claim 9:
10. A method for ventilating a cabin of a vehicle comprising:
drawing in air from the cabin into one or more seat return ducts disposed below one or more seats included within the cabin;
conveying the air from the one or more seat return ducts to one or more lower main ducts extending along a length of the vehicle;
receiving the air from the one or more lower main ducts at an air processing unit (APU) and conditioning the air within the APU;
conveying the air from the APU to one or more upper main ducts extending along the length of the vehicle, the one or more upper main ducts being in fluid communication with a segmented plenum comprising a plurality of sub-plenums separated and sealed from one another by partitions;
injecting the air separately into each sub-plenum from the one or more upper main ducts;
balancing air pressure in the plurality of sub-plenums disposed above and separated from the cabin by a perforated panel; and
ejecting the air from the plurality of sub-plenums through the perforated panel such that a high volume, low turbulence blanket of air descends through the cabin.
