An aspect includes a system for pre-start motoring synchronization for multiple engines of an aircraft. The system includes a first engine starting system of a first engine and a controller. The controller is operable to synchronize a motoring time of the first engine starting system with one or more other engine starting systems of one or more other engines of the aircraft by extending the motoring time of the first engine starting system to match, within a synchronization tolerance, the motoring time of the one or more other engine starting systems in a pre-start motoring sequence. 1. A system for pre-start motoring synchronization for multiple engines of an aircraft , the system comprising:a first engine starting system of a first engine; anda controller operable to synchronize a motoring time of the first engine starting system with one or more other engine starting systems of one or more other engines of the aircraft by extending the motoring time of the first engine starting system to match, within a synchronization tolerance, the motoring time of the one or more other engine starting systems in a pre-start motoring sequence.2. The system as in claim 1 , wherein the motoring time of the first engine starting system is synchronized with the one or more other engine starting systems by comparing an initial value of the motoring time of the first engine starting system with an initial value of the motoring time of the one or more other engine starting systems and selecting a largest value as the motoring time for the first engine starting system and the one or more other engine starting systems.3. The system as in claim 2 , wherein the controller provides the initial value of the motoring time of the first engine starting system to one or more other controllers and receives the initial value of the motoring time of the one or more other engine starting systems from the one or more other controllers.4. The system as in claim 2 , wherein the controller maintains ...
