Jet II,
Thanks for this...I was always wondering how the cabin pressure would be regulated when going to high alt airports. Typical cabin pressure is meant to be from 6000 (B787) to 8000 (others) feet.
You get to Cuzco (10,800) or Lizha, (11,700) and levels on approach to 200' above field level... (with cabin warnings at 8000') All good for airports less than the respective pressures...but. My brain hurtz.. Thank goodness for the automation, because if that ever gives up and one has to adjust this manually....damn.
They had oxygen bottles everywhere (and coca leaves) but nothing on the flightdeck.
Back to OP. It is not a structural issue, in fact, the structure would be far better off without the stress associated with overpressurization
