Zusammenfassung:A system (100) and method (500) for controlling an aircraft propeller (30) are provided. In anticipation of a condition in which a parameter related to an angle of a plurality of blades of the propeller (30) reaches a value beyond a predetermined threshold, a first control signal is output comprising instructions to actuate a feather valve (102) operatively coupled to an actuator (103) configured to adjust the angle in response to hydraulic pressure, thereby causing the feather valve (102) to provide the hydraulic pressure to the actuator (103) and the angle to be adjusted for bringing the parameter towards the threshold. When the parameter reaches the predetermined threshold, a second control signal is output comprising instructions to hold the feather valve (102) at a position in which the hydraulic pressure is withheld from the actuator (103), thereby causing the angle to remain unchanged.
