Verfahren und System zur Charakterisierung und Zählung von Überschreitungen eines Schwellwerts durch einen Funktionsparameter eines Flugzeugmotors

The method involves detecting the threshold exceedance by an operating parameter e.g. exhaust gas temperature, of a gas turbine engine of an aircraft e.g. airplane, during operation of the engine. An alert message relative to the exceedance is automatically transmitted to a ground-based data processing system i.e. computer, by the aircraft based on the exceedance detection. A severity exceedance level is automatically determined from the alert message. A counter representing number of times at which the operating parameter exceeds the severity exceedance level, is measured. An independent claim is also included for a threshold exceedance characterizing and counting system comprising a determination unit.
