|Quoting ACDC8 (Reply 2):|
Cabin air pressure is usually set at 8000 feet. The new B787 is supposed to have cabin air pressure set at 6000 feet
|Quoting Troubleshooter (Reply 3):|
The pressurization system of the ERJ for example maintains a cabin altitude of 8000 ft at FL370. Then you have max. differential pressure of 7.8 PSI.
|Quoting Loggat (Reply 5):|
I typically see 7.4 PSI with cabin altitudes around 4-5 thousand
|Quoting PhilSquares (Reply 9):|
Just to give some idea of cabin pressure. On a recent, yesterday, flight from SIN-SEL we had a cruise altitude of FL370. Our cabin pressure was 4300' the cabin differential was 8.6psi.

Thank you to you and your airline for being generous with the air!
|Quoting Santhosh (Reply 16):|
Are spring loaded valves used in the cabin to release the pressure if it exceeds the nominal value of cabin pressure?
