Abstract
An assembly for an aircraft propulsion system includes a propeller, a blade position sensor, and a controller. The propeller is configured for rotation about a rotational axis. The propeller includes a plurality of propeller blades. The plurality of propeller blades have a pitch. Each propeller blade of the plurality of propeller blades is configured for rotation about a respective lengthwise axis to selectively vary the pitch. The blade position sensor is configured to measure the pitch. The blade position sensor is configured to generate a pitch output signal representative of the measured pitch. The controller is in signal communication with the blade position sensor. The controller includes a processor in communication with a non-transitory memory storing instructions, which instructions when executed by the processor, cause the processor to: detect a presence or an absence of an erroneous propeller blade pitch measurement using at least the pitch output signal.
