Abstract
A method of monitoring oil level in a tank of an aircraft engine, including: for at least two predetermined operating stages of the engine, during at least one mission of the aircraft: obtaining a plurality of measurements of an oil level of the tank, each measurement being associated with an oil temperature and with an engine speed of rotation, and selecting measurements representative of oil level variations and associated with oil temperatures that are close to a reference temperature and with engine speeds of rotation that are close to a reference speed of rotation; aggregating the measurements selected over the operating stages and during the at least one mission of the aircraft; and comparing the aggregated measurements with reference data to identify abnormal oil consumption of the engine.
