Fuel metering unit for an aircraft engine

A fuel feed control and protection system for an aircraft engine, comprising

• an engine control computer generating a fuel mass flow rate setpoint;
• and
• a fuel metering unit for the aircraft engine, comprising
• a metering member configured to receive a control signal and to meter the fuel feed of the engine depending on said control;
• a cutoff member configured to cut off the fuel feed of the engine;
• wherein the fuel metering unit further comprises a protection and cutoff computer of the engine, configured to:
• receive data allowing evaluating the instantaneous value of the engine speed;
• compare the instantaneous value of the engine speed to a predefined engine speed threshold value and determine a possible overspeed state on the basis of this comparison;
• and
• transmit a control signal to a cutoff control member contained in the cutoff member to cut off the fuel feed of the engine if an overspeed state of the engine speed is determined.
