A method of discriminating between spurious and genuine surges in a gas turbine engine is disclosed which includes the steps of receiving an engine speed signal over a global engine surge investigation region having a plurality of temporal regions in which engine surge events can occur, identifying a specific temporal region in which an engine surge event occurs, incrementing a surge counter corresponding to the temporal region in which the engine surge event occurred by a magnitude of two, identifying the temporal regions in which no engine surge event occurred, decrementing a surge counter corresponding to each temporal region in which no engine surge event occurred by a magnitude of one; and enabling a surge avoidance flag when the magnitude of the surge counter has reached a predetermined value.
