Method and system for monitoring the level of oil contained in a tank of an aircraft engine
Abstract
one. The way to control the oil level, contained in the tank (21) of the aircraft engine, moreover, the method comprises the steps on which for at least, two predefined phases of the engine, during, at least, one flight of an aircraft - receive (E10) many measurements of the oil level in the tank, moreover, each measurement is associated with oil temperature and engine speed, and - choose (E50-E70) measurements, representing changes in oil level and associated with oil temperatures, which are close to the reference temperature, and with engine speed which are close to the reference speed, - combine (F40) measurements, selected by the phases of work and during the aforementioned, at least, one flight of an aircraft and - compare (F60) the combined measurements with the reference data to identify (F70) the abnormal engine oil consumption. 2. The control method according to claim 1, in which two predetermined phases of the engine operation correspond to the taxiing phase and the cruising phase in flight of the aircraft (E30). The control method according to claim 1, in which, when selecting measurements, measurements representing changes in oil level obtained over a time shorter than a predetermined limit duration are excluded (E60). The control method according to claim 1, in which, when choosing measurements, measuring the oil level exceeding a predetermined maximum oil level, exclude (E60) .5. The control method according to claim 1, in which, when selecting measurements, measurements representing changes in oil level exceeding a predetermined limit change are excluded (E60) .6. The control method according to claim 1, in which the combination of measurements includes
