Abstract
A fuel inerting system, comprising a first supply means (2) to supply an inert gas to a fuel tank (8) to scrub the fuel therein when the ullage (16) of the fuel tank is inert, and a second supply means (4) to supply the inert gas to scrub the fuel (6) therein when the ullage of the fuel tank is not inert, the first and second supply means (2, 4) being individually operable by means of a valve arrangement (10), in such a manner that only one of the supply means is operable at any given time. The inert gas consists of nitrogen enriched air, produced by passing air from a pressurized area of the aircraft through a nitrogen separator located within, but removable from, the aircraft.
