Patent number: 11286806Abstract: There is described herein methods and systems for testing a propeller feathering function. The method comprises monitoring a rotational speed over time of propeller blades of an aircraft, commanding an angle change of the propeller blades, comparing a post-angle change rotational speed of the propeller blades to an expected rotational speed without the commanded angle change and obtaining, by the processor, a rotational speed difference, and issuing a test passed signal when the rotational speed difference exceeds a threshold and a test failed signal when the rotational speed difference does not exceed the threshold.Type: GrantFiled: October 17, 2019Date of Patent: March 29, 2022Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Brant Duke, Kenneth Matheson
