|  cabin pressure
hello everyone, I was wondering, when you take off do your ears pop? I'm talking about the pilots, cause when i fly my ears pop. An I would think it would be kind of hard to listen to ATC if your ears are poping so what do you pilots do if any thing at all that make your ears not pop? |

Yes, my ears pop just like everybody else. After a while you don't even notice, it becomes like second nature to pinch your nose and clear your ears while descending. Light planes are not pressurized, so every small change in altitude causes your ears to pop. Inside a airliner the cabin is pressurized so it's not as bad as a light plane. Most airliners maintain a miximum of 8 psi pressure diferential inside the cabin compared to outside. This useually give the cabin an effective altitude of 8,000ft, while cruising at 35K. |

[ QUOTE ] A Valsalva maneuver is a forced expiration against the nose and mouth held closed. Also known as Valsalva's test and Valsalva's method, it is named after Antonio Maria Valsalva , a famous Italian anatomist. <snip> The Valsalva maneuver is used as a pressure equalisation technique by scuba divers and aeroplane passengers to avoid barotrauma and discomfort inside their ears when they move to or from a higher pressure breathing environment. A person using this pressure equalisation technique pinches their nose, closes their mouth and tries to exhale. The technique works by raising the pressure in the throat so that a small volume of air moves from the throat to the ears through the Eustachian tube, which connects the two.

I also think when you are doing it so much, you take it of before you really notice it.
