Submission + - Why does air pressure fluctuate in airplanes?

TimFreeman writes: "Commercial airlines have machinery for controlling the pressure in the air cabin. I assume this machinery can give them any pressure they want, so they could have the pressure in the plane change smoothly from the ground-level air pressure at the takeoff point to the ground-level air pressure at the destination. Instead, the pressure goes down when they take off and back up when they land. When I flew with blocked eustacian tubes four days ago, it hurt like hell, every takeoff and landing, and my right ear still hasn't healed.

Why do they permit the pressure fluctuation?"
