There is provided a blade angle feedback assembly for an aircraft-bladed rotor rotatable about a longitudinal axis and having an adjustable blade pitch angle. The assembly comprises a feedback device coupled to rotate with the rotor, the feedback device having a root surface having a first edge, first position markers extending from the root surface and oriented substantially parallel to the axis, the first position markers circumferentially spaced from one another, at least one second position marker extending from the root surface and positioned between two adjacent first position markers at an angle thereto, the at least one second position marker having an end positioned adjacent to the first edge and non-flush therewith, and at least one sensor mounted adjacent the feedback device and configured to detect a passage of the first position markers and the at least one second position marker as the feedback device rotates about the axis.
