There is produced (at 2) air enriched in inert gas, from a source (9) of compressed air internal to the aircraft, and this enriched air is admitted (via 10) into the fuel tank (12). During the cruising phase of the aircraft, there is produced a first fraction of air having a first inert gas content, and this first fraction is admitted into the fuel tank (12) at a first flow rate. Moreover, during the descent phase, there is produced a second fraction of enriched air having a second inert gas content substantially less than the first content, and the second fraction is admitted to the reservoir (12) at a second flow rate substantially greater than the first flow rate.
