How do you check the blade angle propeller of aircraft?
Propellers are measured in stations. This is done by first finding the propeller station number where the angle measurements are taken. Stations are measured in inches from the center of the propeller hub. As an example; propeller station 35 would be 35 inches from the center of the hub. The propeller maintenance manual and/or the Type Certificate Data Sheet for the specific propeller will provide the station number. Once you have located the proper station a propeller protractor is used to measure the angle. The protractor must first be "zeroed" (normally at the hub). Then the angle will be checked on the "Face" of the blade (this is the side that "faces" the pilot when sitting in the pilot seat). This must be done on each blade of the propeller to ensure they are all the same (or within limitations set by the manufacturer).
