Beschreibung
Zusammenfassung:	The present invention relates to a method for monitoring the operating state of a hydromechanical unit (100) of an aircraft turbomachine, comprising: a metering valve (130) comprising a mobile metering part (138), a regulating valve (140) configured to control the flow rate (Q) through the metering valve (130), a flow meter (150) able to measure the mass flow rate (Q) of fuel passing through, characterized in that a monitoring module (300) is configured to implement the following steps: (E20') determine a reconstructed flow rate on the basis of the position of the mobile part (138), and determine a measurement of the density of the fuel, - (E30) calculate a remnant, and compare said remnant to a determined threshold value, (E90) determine a state of abnormal operation of the hydromechanical unit dependent on the result of the comparison. 本发明涉及一种用于监测飞行器涡轮机的液压机械单元(100)的运行状态的方法，包括：包括可移动计量部(138)的计量阀(130)；调节阀(140)，配置为控制通过计量阀(130)的流速(Q)；流速计(150)，能够测量通过的燃料的质量流速(Q)，其特征在于，监测模块(300)被配置为执行以下步骤：(E20')基于可移动部(138)的位置来确定重建流
