1. A method for evaluating a condition of an engine, the method comprising:
- obtaining a sample signature of a first engine, the sample signature characterizing the first engine as a function of a fluid sample of the first engine;
comparing the sample signature to a plurality of reference signatures obtained from reference engines belonging to a common family with the first engine;
selecting ones of the reference engines for which a difference between a corresponding reference signature and the sample signature is below a threshold; and
providing historical engine data of the selected ones of the reference engines as a basis for evaluating the condition of the first engine;
wherein the difference between the corresponding reference signature and the sample signature is found using;

Abstract
There is described herein methods and systems for comparing an engine fluid signature of a first engine with engine fluid signatures of other engines of a same engine family. A delta signature is obtained via the comparison and delta signatures below a given threshold are considered similar. Historical data for each engine having a similar signature may then be used to determine the condition and the future states of the first engine.
