Abstract The present invention relates to a method for detecting performance of an APU starter, comprising: obtaining APU-related messages at multiple time points within one time period; obtaining running parameters of the APU starter according to the messages, the running parameters comprise starting time STA; calculating average value AVG and deviation index .delta. of the starting time within said time period; determining whether performance of the APU starter is in a stable phase, decline phase or failure phase according to the deviation index .delta.. La présente invention concerne un procédé pour détecter la performance dun démarreur de groupe auxiliaire de bord, comprenant : lobtention de messages reliés au groupe auxiliaire de bord à de multiples points dans la durée dune période; lobtention de paramètres de fonctionnement du démarreur de groupe auxiliaire de bord selon les messages, les paramètres de fonctionnement comprenant un algorithme STA de lheure de début; le calcul dune valeur moyenne du groupe auxiliaire de bord et de lécart dindice .delta. de lheure de début au cours de ladite période; la détermination si la performance du démarreur de groupe auxiliaire de bord est dans une phase stable, une phase décroissante ou une phase déchec selon lécart dindice .delta..
