Aircraft power and propulsion systems 100 and methods 300 of operating such power and propulsion systems 100 are provided. One such method 300 comprises: operating one or more electric machines 111, 112 of one or more gas turbine engines 110; 110a, 110b as generators to extract mechanical power from one or more of spools 16, 19, 26; 15, 17, 27 and generating electrical power therefrom; meeting an electrical power demand, PD, of a plurality of electrical loads 115, 116, 150 connected with an electrical system 120 by supplying the plurality of electrical loads with electrical power generated by the one or more electric machines 111, 112; determining a condition to the effect that there is a fault in the electrical system 120 and/or one or more of the one or more gas turbine engines 110; 110a, 110b and that an amount of electrical power being generated by the power and propulsion system 100 has reduced to a lower level, Pfault; and responsive to the determination: during a time period ΔT, controlling the plurality of electrical loads 115, 116, 150 to reduce the electrical power demand; and during the time period ΔT, meeting at least part of the electrical power demand of the plurality of electrical loads 115, 116, 150 by discharging the electrical energy storage system 130.
