A gas turbine engine system includes a gas turbine engine, an electric machine, a fuel pump, and a clutch arranged to selectively couple and decouple the electric machine and the fuel pump with the gas turbine engine. Control circuitry may control the clutch in response to data signals indicating engine operating information, current operating conditions, and/or other information.
