An inerting system of a fuel tank of an aircraft includes an air separation module supplied at the inlet with air at a certain pressure to generate at the outlet an inert gas to be injected into the fuel tank comprising a certain flow rate and a certain oxygen concentration. A control method includes, at a given instant and at a constant air temperature and atmospheric pressure, (1) reducing the inert gas flow rate to a determined value, and (2) reducing the air pressure in order to cause an increase in the oxygen concentration from an initial value to a determined value. Decreasing the inert gas flow rate is performed by compensating for a loss of inert gas flow caused by the air pressure reduction, and decreasing the air pressure is performed by compensating for a reduction in the oxygen concentration caused by the inert gas flow rate reduction.
