Zusammenfassung:	The invention proposes a method for determining the capacity of an aircraft pump to deliver a predetermined fuel flow rate, characterised in that it comprises a step of rotating the pump at a predetermined speed; a step of supplying at least one cylinder with the totality of the fuel coming out of the pump; a step of determining the fuel flow rate supplying said cylinder, and a diagnostic step which consists in determining whether the pump is able to supply a sufficient flow rate as a function of the determined value of the flow rate supplying the cylinder. The invention also proposes a device implementing the method.
