Abstract
A drain assembly for aircraft which is operable to provide a drainage outflow course for discharge of cabin collecting liquids in an aircraft to the outside environment when the aircraft is at ground level or operating at altitudes up to a certain height but which is operable to seal tight that drainage course when the aircraft is operating above that certain height so that cabin depressurization cannot occur through the drainage course.
