Passenger Metabolism and Increasing CO2 Production

Carbon dioxide (CO2) gas production into the coach cabin is a function of collective passenger metabolism. Different passengers produce this gas at different rates. Larger size and metabolically active passengers will produce more CO2.

Metabolically Active Passengers:

  • Re-arranging seating preferences
  • Stowing away luggage
  • Getting to know neighbor
  • Shocked at little seat space

Heightened CO2 production may occur mostly during the metabolically active boarding and initial “get-to-know your neighbor” period of enplanement.

Metabolically active passengers are producing much CO2. Yet…it is during this boarding & enplanement phase that airlines infuse the least amount of fresh air.

And…

Until the pilot expends some resources to cool down the cabin, passengers will feel uncomfortable.
