there is proposed a method for controlling a bistable shutoff vale for an aircraft engine , involving the steps of : emitting a closure signal on one of the control channels — emitting an open signal on the other control channel , the method being characterized in that — the amplitude of the close signal is designed to cause the vane to move into a first position constantly in a given period of time ,— in the same period , the amplitude of the open signal fluctuates between a value designed to urge the valve toward a second position and a rest value , the actuating values of the two signals being adapted to one another in order to keep the vane immobile when the two signals received by the valve simultaneously adopt said actuation values .
