Methods and systems for validating a propeller control unit (200) associated with a propeller (19) having blades (17) are provided. Actuation of a control valve (202) of the propeller control unit (200) is commanded to alter a pitch angle of the blades (17). One of an actual pitch angle of the blades (17) and an actual rotational speed of the propeller (19) is determined after a predetermined time delay has elapsed. The one of the actual pitch angle of the blades (17) and the actual rotational speed of the propeller (19) is compared to a corresponding one of a pitch angle threshold and a rotational speed threshold, the pitch angle threshold and the rotational speed threshold based on a commanded pitch angle. A warning signal is issued in response to determining one of the actual pitch angle failing to meet the pitch angle threshold and the actual rotational speed failing to meet the rotational speed threshold.
