Boeing 737-800 Cabin pressure logged

Postby Martin on Mon Nov 04, 2013 1:36 pm

Motec CDL3 with absolute pressure sensor connected to it.
Start of file, Cape Town airport, Altitude 42m
End of file, Lanseria airport, altitude 1372m

Aviation laws state that pressurized cabins (passengers) may not be less than 75KpaA duting a flight, regardless of the altitude. Higher cabin pressures = more air frame stress. I think for this reason airlines will run it as close to 75KpaA as possible.

Maybe someone will find this interesting,,,

Pretty cool.
I think I'd rather have a little less to breath than have the air frame come apart (as the DeHaviland Comet did).
