In airliners, cabin altitude during flight is kept above sea level in order to reduce
stress on the pressurized part of the fuselage; this stress ...
Airplanes are at their best up high, where the air is thin and smooth. ... At first,
fliers coped by filling tanks with pressurized oxygen and inhaling the gas through
Airplanes that go long distances and want to do so economically want to be at
high altitudes. But humans can't get enough oxygen perfusion in our blood if th...
Although aircraft cabins are pressurized, cabin air pressure at cruising altitude is
lower than air pressure at sea level. At typical cruising altitudes in the range 11 ...
Large transport-category and high performance passenger aircraft pressurize the
air in the cabin. This serves to push more of the normal 21 percent oxygen ...
Oct 10, 2014 ... Cabin pressurization changes throughout the flight. On the ground at sea level
the plane is pressurized to -100 - -300ft, so a higher pressure ...
Apr 12, 2011 ... Last week the world was treated to an unexpected spectacle – the sight of an
airplane cabin with a big hole in it open to the sky. We can ...

what happens with pressurized airplane cabins.
Pressurized Airplanes. When an airplane is flown at a high altitude, it consumes
less fuel for a given airspeed than it does for the same speed at a lower altitude.
Most aircraft cabins are pressurized to 8,000 feet above sea level, an altitude that
lowers the amount of oxygen in the blood by about 4 percentage points, ...
