Abstract: A power system is provided that includes a plurality of engines and a compressed air source in communication with the plurality of engines and configured to assist in starting the engines. A plurality of engine controllers are provided each associated with a respective one of the plurality of engines. The engine controllers are communicatively linked with each other and upon receipt of a signal to start the plurality of engines are configured to stagger the starts of the plurality of engines according to a predetermined order and to apply an air start system charge delay timer before starting an individual engine when the compressed air source is in a first state in which the compressed air source is unable to assist starting at least one of the plurality of engines.
