Modeling dynamic systems such as engines and their control systems involves accounting for linkages, components and the engine designs themselves, where each have their own unique dynamic behaviors and response times that all affect how the overall system responds to inputs and impulses. This Start/Spool Tab is used to configure parameters and model various components that affect the Starting and Spooling Behavior of engines.

Spooling refers to the acceleration / deceleration of turbine spools between idle and their max RPM. Turbine accelerations are called Spooling up and turbine decelerations Spooling Down.
