Propeller control systems (200) and methods for controlling the pitch of a plurality of propeller blades (150) of a variable pitch propeller assembly (106) operatively coupled with an engine (100) is provided. In one exemplary aspect, the propeller control system includes features for combining overspeed and feathering protective functions in a protective control valve (240) communicatively coupled with a controller (250). In such an event the controller controls the protective control valve to selectively allow a controlled amount of hydraulic fluid to flow to or from a pitch actuation assembly (202) such that the pitch of the propeller blades can be adjusted based at least in part on the condition of the engine.
