Question

1. (EEAR/2018)
PRESSURE
Jeremy Berke Commercial airplane cabins are generally pressurized to an
equivalent of 6,000 to 8,000 feet above sea level, in an effort to maintain
a
healthy oxygen level for both the passengers and the flight crew. When a
passenger jet is flying at a cruising altitude of over 36,000 feet, the pressure
outside the cabin is
than inside the pressurized cabin. Air
pressure has a tendency to equalize, moving from areas of high pressure to low
pressure to achieve equilibrium. When a hole rips open on a plane, the suction
resulting from the pressure difference between the cabin and the sky could pull
nearby people or objects outside. Depending on the size of the hole, such
accidents could either create just enough force to shuffle papers around, or, pull
a full-size human out of the plane. Survival is unlikely for anyone fully sucked
out into the sky. While in-flight incidents are extremely rare, if you want to​
