Pasquale Sforza, in Commercial Airplane Design Principles, 2014 3.2.2 Cabin pressureĪt the normal stratospheric cruising altitudes of 30,000–38,000 ft, the outside pressure is 0.3–0.2 atm, respectively, while the cabin pressure is maintained at a level equal to that found at altitudes between about 5500 ft and 8000 ft, or between about 0.8 and 0.7 atm.
