A blade angle feedback assembly (200) for an aircraft-bladed rotor (130) and an aircraft-bladed rotor system are provided. The rotor (130) is rotatable about a longitudinal axis (A) and has an adjustable blade pitch angle. A feedback device (204) is coupled to rotate with the rotor (130), the feedback device (204) having a root surface (304) having an edge (3021, 3022). At least one position marker (202) extends from the root surface (304) and extends laterally beyond the edge (3021, 3022). At least one sensor (212) is mounted adjacent the feedback device (204) and configured to detect a passage of the at least one position marker (202) as the feedback device (204) rotates about the longitudinal axis (A).
