Also, the packs would be working their ass off to keep pressures that high.
|Quoting Grbld (Reply 4):|
. Even though the limits seem mighty close, you'll have to realize that at those altitudes, outside air pressure doesn't change much, so a bit of extra strength can give you a much lower cabin altitude at the same level.
Air pressure at just 18,000 ft is about half of that at sea level.
|Quoting Lehpron (Thread starter):|
For example: If I had a plane where the max operating pressure in the cabin (not ultimate) is 10 psi, and the plane were pressurized to 5000 feet, what altitude could it go to regardless of what the wings could do?
