A system of pressure control for an environment to be pressurized includes a controller configured to calculate an environment leakage effective area CdALEAK according to: CdALEAK = f(Pc, Tc, Pa, WLEAK) wherein Pc is an environment pressure; Tc is an environment temperature; Pa is an ambient pressure outside of the environment; WLEAK = WECS - WOFV - WAPU; wherein WECS = air pressure inflow into the environment; WOFV = air pressure outflow to ambient that is outside of the environment; WAPU = f(Tin, Pin, APURPM, Flowfuel); wherein Tin = inlet temperature to a power source; Pin = inlet pressure to the power source; APURPM = rotational speed of the power source; Flowfuel = power source fuel flow. A processor is in communication with the controller and configured to compare a current CdALEAK value with a control limit; wherein the control limit is based on historical CdALEAK values.
