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.

Abstract: A device and method for monitoring a high-pressure pump in a turbomachine fuel supply circuit by detecting opening of a pressurizing and shut-off valve mounted on an outlet side of a fuel flow regulating valve, by measuring rotational speed of the turbomachine corresponding to the opening of the pressurizing and cut-off valve, and by monitoring change in a value of the rotational speed to propose replacement of the high-pressure pump when the measure value rotational speed reaches a predetermined threshold.

Abstract: A method for monitoring engines of a plane, including at least two engines, each engine being controlled and monitored by an engine monitoring calculator, the calculators being connected to each other by a communication network and each calculator monitoring operating parameters of one engine. The method being characterized in that both calculators output on the network the value of at least one of the parameters for comparison with the same parameter outputted by the other calculator, and if a value of one calculator deviates from a value of the other calculator by a difference higher than a predetermined threshold, one of the engines is diagnosed as operating abnormally.

Abstract: The method of the invention for monitoring a thrust reverser of a turbojet having an actuator controlled by an electric motor consists in determining a maintenance notice from a weighted combination of provisional notices, each provisional notice relating to a category of parameters associated with at least one phase of an operating cycle of the reverser, the category being selected from a category of parameters representative of a duration of said phase, of an energy seen by the motor during said phase, of a torque seen by the motor at a predefined instant of said phase, and of a duration during which the setpoint speed of rotation and the measured speed of rotation of the motor differ during said phase, each provisional notice being generated by analyzing values obtained during at least one cycle for at least one parameter of said category relative to a degradation threshold.

Abstract: A method for monitoring plane engines The present invention relates to a method for monitoring engines of a plane comprising at least two engines (m1, m2, m3, m4), each engine (m1, m2, m3, m4) being controlled and monitored by an engine monitoring calculator (1, 2, 3, 4), said calculators (1, 2, 3, 4) being connected between them by a communication network (5) and each calculator (1, 2, 3, 4) monitoring the operating parameters (p, V) of the engine (m1, m2, m3, m4) it monitors. The method is characterized in that both calculators (1, 2, 3, 4) emit (60; 100) on the network (5) the value (V(k)) of at least one of said parameters (p(k)) for being compared (62; 102, 103, 104) with those (V(k?)) of the same parameter (p(k) p(k?)) emitted by the other calculator (1, 2, 3, 4), and in that, if a value (k)) deviates from the other (V(k?)) by a difference (d1(k), d2(k), d3(k)) higher than a predetermined threshold (S), one of the engines (m(k)) is diagnosed as being in an abnormal operation.
