  • Good video, thanks a lot!

  • Question??

    most of airplanes get fresh air inside by compressing outside air with their jet engine. What if the plane have a propeller engine instead?

  • But what about AIR PRESSURE? You have explained very well the reduced humidity, but the big change in the passenger's environment is the loss of cabin air pressure. What effect does this loss of 200 mmHg have on the passengers? At sea level air pressure is 760 mmHg and at 8,000 ft it is only 560 mmHg. Our body tissues are in a constant state of pressure equilibrium with our surrounding air pressure. .This tissue depressurization is the passenger's major physical challenge.
