Abstract
A method of starting an aircraft engine is provided. The method includes providing motive power from a generator for starting an engine during an engine start mode and deriving electrical power by way of the generator from rotation of the engine during a generate mode, transmitting the motive power from the generator to the engine during the engine start mode by way of a constant speed drive (CSD) and regulating a frequency of the electrical power output from the generator during the generate mode by way of the CSD and coupling a generator and CSD controller (GCC) to the generator and the CSD and operating the generator and the CSD by the GCC to execute at least the engine start mode and the generate mode.
