Purpose: This SAFO advises about the potential for un-commanded feathering events when Propeller Control Units (PCU) and adapters are improperly repaired or overhauled. As the reset lever is pushed up by the flyweights/ speeder spring cup, the Py air bleeds from the fuel control unit (FCU) which lowers the fuel flow, engine power, and thus propeller speed. nWe can supply two different types of pitch control units. Photo may represent series and not specific product; SHARE; PCU 5000 Propeller Control Units. In a constant speed prop, the prop control lever basically changes the speed of the prop (it is not always running at the same speed as you indicate in your question, but rather once the speed is changed by the prop control lever, the governor keeps it at that speed). These airframe It's the propeller control, and when you fly a plane with a constant speed propeller, it gives you the ability to select the prop and engine speed you want for any situation. In reverse, propeller speed remains 5 percent below the selected propeller speed so that the control valve remains fully open, and only the beta valve controls the oil flow to the propeller dome.
