Abstract: The invention relates to a device for monitoring the lifetime of at least one hydraulic apparatus of an aircraft that is subject to ventilations in hydraulic pressure during flight, comprising an interface for receiving measurement data which are representative of hydraulic pressure (P).

Abstract: The invention relates to a method for detecting a possible fuel leak into an oil circuit of an aircraft engine, the aircraft including at least one pair of identical engines equipped with respective oil circuits, the pair of engines being associated with at least one quadruplet of measurements previously acquired in a measurement time during the operation of the engines of the pair and corresponding to a measurement of pressure and a measurement of temperature of the fluid contained in each of the oil circuits of the engines of the pair.

Abstract: A method for synchronizing data frames, including an initialization phase storing the frames received on each of links in a buffer memory dedicated to the link, the frames stored in a first position of a second buffer memory dedicated to a second link and a first position of a third buffer memory dedicated to a third link including a same predefined identification number, and a first buffer memory dedicated to a first link storing a number of frames equal to the smallest multiple of a first predefined number greater than or equal to double the number of frames received on one of the second or third links, and an operation phase storing the frames received on each of the links in the buffer memories, each frame stored in a position on the second buffer memory including the same identification number as the frame stored at the same position of the third buffer memory.
