A method of determining whether it is necessary to inert an aircraft fuel tank (11, figure 2) is provided. The method comprises providing a temperature value 101 indicative of a temperature of the fuel (F) in a fuel tank after refueling, and based on said temperature value, determining 102 whether or not it is necessary to inert the aircraft fuel tank. A method of controlling the supply of inerting gas to the fuel tank is also provided, as is an aircraft fuel tank inerting control system (200). Also provided is a method comprising providing a temperature value indicative of the highest temperature at the aircraft's predicted departure date and departure location. The method may comprise determining whether or not it is necessary to inert the fuel tank for all of the immediately forthcoming flight. Also provided is a method of determining whether or not to remove one or more parts of an aircraft fuel tank inerting arrangement based on an estimation of whereabouts of the aircraft over a period of four weeks.
