FIELD: transport.
SUBSTANCE: invention relates to aircraft engine control hardware, particularly, to faultfinding. For identification used are means for determination of the set of normalised indicators that represent the operation of aircraft engine. Means are used to construct the abnormality vector describing the engine behaviour as the function of said set of normalised indicators. Means are used to select, in the case of abnormality detected by said abnormality vector, the subset of basic vectors with directions that belong to definite neighbourhood of direction of said abnormality vector. Said subset of basic vectors is selected from the set of basic vectors content-related with faults of said engine. Saud faults are defined using the criteria set of experts. Besides, means are used to identify faults content-related with said subset of basic vectors.
EFFECT: accelerated identification.
