A method and system for surge detection within a gas turbine engine, comprises: measuring the compressor discharge pressure (CDP) of the gas turbine over a period of time; determining a time derivative (CDP ) of the measured (CDP) correcting the CDP for altitude, (CDP ); estimating a short-term average of CDP ; estimating a short-term average of CDP ; and determining a short-term variance of corrected CDP rate of change (CDP ) based upon the short-term average of CDP and the short-term average of CDP . The method and system then compares the short-term variance of corrected CDP rate of change with a pre-determined threshold (CDP ) and signals an output when CDP >CDP . The method and system provides a signal of a surge within the gas turbine engine when CDP remains>CDP for pre-determined period of time.
