Zusammenfassung:	A method 300 for operating a gas turbine engine having a starter-electric generator (108) driven by one of a plurality of shafts of the gas turbine engine is provided. The method includes determining 302 a desired amount of thrust to be produced by the gas turbine engine, as well as a desired amount of electrical power 304 to be drawn from the starter-electric generator (108) of the gas turbine engine. The method operates the gas turbine engine to produce 306 the desired amount of thrust, while drawing 308 less than the desired amount of electrical power from the starter-electric generator (108). Drawing less than the desired amount of electrical power from the starter-electric generator (108) allows for the desired amount of thrust production, allows for the desired amount of thrust production more quickly, or allows for maintenance of a stall margin for any purpose (such as to increase an efficiency of the engine or to allow for certain engine designs).
