Abstract: A method for monitoring the change in state of a valve in a start up circuit of a turbo-engine following a command to change the state of the valve includes measuring the air pressure under a fan cowl of the turbo-engine before the change state command, measuring the air pressure under the fan cowl after the change state command, comparing the measured values of the air pressure, and determining whether or not the valve has actually changed state. An aircraft turbo-engine includes a unit that monitors the change in the valve using such a method.

Abstract translation: 一种用于监视涡轮发动机的起动电路中的阀的状态变化的方法，其特征在于，在改变所述阀的状态的指令之后，包括在所述改变状态指令之前测量所述涡轮发动机的风扇罩下的气压 ，在改变状态命令之后测量风扇整流罩下方的空气压力，比较测量的空气压力值，并确定阀门是否已经实际改变状态。 飞机涡轮发动机包括使用这种方法监测阀的变化的单元。
