Abstract: A method of starting a turbine engine utilizing multiple components. The turbine engine may comprise a gearbox coupled to a spool of the turbine engine via an output shaft. A first starter may be coupled to the gearbox via an input shaft. A first accessory may be coupled to the gearbox via another input shaft. The rotation of the output shaft of the gearbox may be coupled to the rotation of the spool. The rotation of each of the first starter and first accessory may be coupled to the rotation of the respective input shaft of the gearbox. The method may comprise applying a first application of power to one of the first starter and the first accessory and applying a second application of power to the other of the first accessory and the first starter.
