A method of generating oxygen depleted air on an aircraft includes the steps of passing a first proportion of air through an air pressure reduction device 70 to produce a supply of reduced pressure air. A second proportion of air is passed along one side 64 of a membrane 68 of an air separation module 60, exposing the other side 66 of the membrane 68 of the air separation module 60 to the reduced pressure air. Oxygen is extracted from the second proportion of air across the membrane 68 and the air separation module 60 exhausts oxygen depleted air for inerting an aircraft fuel tank 40.
