This paper proposes a method for interpretation of helicopter condition monitoring indicators, focusing on trend analysis rater than traditional magnitude thresholds. The method analyzes the stationarity of each indicator, and compares trend activity to a threshold database generalized to cover all aircraft of a specific model. This avoid the problem of individual threshold setting for each aircraft
