There is produced (at ) air enriched in inert gas, from a source ( ) of compressed air internal to the aircraft, and this enriched air is admitted (via ) into the fuel tank ( ). 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 ( ) 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 ( ) at a second flow rate substantially greater than the first flow rate.
