This article presents a method of diagnosis of avionics equipment based on the temporal correlation of events. A failure is detected thanks to the execution of built-in tests organised in test trees. The method proposed is based on two parameters: the temporal data coming from the test tree execution and the propagation time of failures. The temporal correlation window between the failure messages is obtained thanks to the analysis of the ways of failure propagation. The identification of this time window allows determining the degree of correlation between the different failure messages. The goal is to distinguish between single failure occurrence with propagation phenomenon, and multiple occurrences of failure.
