A system for blade angle position feedback comprises a feedback device (104) and a sensor (112) mounted adjacent the feedback device (104) and configured for detecting a passage of position markers (102) on the feedback device (104) during propeller rotation. The position markers (102) are spaced apart from one another around the circumference of the feedback device (104) and are oriented at an angle to one another and to a longitudinal axis. The feedback device (104) and sensor (112) are configured for relative axial displacement. A detection unit (116) is connected to the sensor for receiving the sensor signal therefrom, determining on the basis of the sensor signal a time interval elapsed between the passage of successive position markers (102), and computing from the time interval blade angle position.
