Why does air pressure difference make us have airplane ears during a flight, if airliners are pressurized?
In: Physics
Other people have commented about the 8000 foot pressurization, so I’ll ignore that in my comment. Another thing to add is that the cabin pressure can rapidly change when the engines spin up or down. Cabin pressure is maintained by bleeding air from the high pressure turbines just before combustion. Even if they are targeting 8000 feet of elevation, this drop or increase in pressure can be felt by your ears.
Its also why one of the first signs of a bird strike is the distinct aroma of fried chicken in the cabin.
