Abstract

A method and system for inerting an aircraft fuel tank is disclosed. A gas separation module (18) is provided comprising a plurality of strands of hollow fibre separation membrane wound around a core. Cabin air (17) is drawn through the membrane bundle and is separated into nitrogen and oxygen enriched fractions by the pressure difference existing between the cabin air and the atmosphere outside of the aircraft. The nitrogen enriched air is then supplied to the fuel tanks to provide an inert atmosphere.
