An input drive arrangement 1 of a generator 3 arranged to be driven by an aircraft engine 2 such as a gas turbine engine. The input drive arrangement comprises a disconnect device 100, such as a clutch, comprising a drive transfer means having a connected configuration and a disconnected configuration. The drive transfer means is configured to transfer a rotational drive between an input shaft of the generator and a rotor of the generator when in the connected configuration, and to disconnect the input shaft from the rotor when in the disconnected configuration. The input drive arrangement further comprises an accessory drive member 128, arranged to rotate with the input shaft to output power to at least one accessory of the generator; wherein the accessory drive member is connected to the input shaft such that it continues to rotate with the input shaft when the drive transfer means is in the disconnected configuration. The accessory drive member may drive a fluid pump, a further generator 194 or a pulley. The pump may be used for providing lubricating or cooling fluid to the system. A further aspect of the present invention provides an aircraft engine assembly and an aircraft comprising the input drive arrangement.
