Abstract

This process comprises a phase for detecting (26) the presence of the fire, as well as a phase for extinguishing this fire, comprising a phase of projecting (by 24), into the compartment (16), an extinguishing fluid, in particular water, as well as a phase of generating (by 2) air enriched in inert gas, from a source (5) of compressed air internal to the airplane, and a phase of admitting (by 10 and 12) at least a portion of this enriched air into the compartment (16).
