A system and method for providing feedback for an aircraft-bladed rotor (130) about a longitudinal axis (A) and having an adjustable blade pitch angle. At least one position marker (502) is provided at the rotor (130), extends along an axial direction, from a first end (5041) to a second end (5042), and has varying magnetic permeability from the first end (5041) to the second end (504z). At least one sensor (212) is coupled to the rotor (130) and configured for producing, as the rotor (130) rotates about the longitudinal axis (A), at least one sensor signal in response to detecting passage of the at least one position marker (502). A control unit (220) is communicatively coupled to the at least one sensor (212) and configured to generate a feedback signal indicative of the blade pitch angle in response to the at least one sensor signal received from the at least one sensor (212).
