Abstract
A frangible aircraft floor includes a floor support having at least one opening formed therethrough. A thin film is positioned with respect to the opening and is provided with a frangible seam which ruptures when a predetermined pressure difference exists on opposing sides of the film to allow increased airflow through the opening to equalize pressure between the compartments in the event of a sudden loss in pressure.
