This is BASIC knowledge for an airline pilot guys!

max cabin pressu: 7 to 9 psi
max ceiling: FL350 to FL 410
max cabin alt: 8000ft
normal rate of cabin climb: 500 to 600fpm
normal rate of cabin descent: 300fpm
etc. etc.

It's just one of those things that are the same on all planes. Maybe these numbers are not as well known, but still they are very important if you want to keep your pax (and yourself) alive up there.


Now, if I'd ask you what would be a typical N1 settng on a normal take off,
a: 25%
b: 60%
c: 90%
d: 105%
what would be your answer? Do you think this is a difficult question? Then what's the problem with this pressurisation question?
