In order to limit the acceleration and speed of jet engine accessory equipment when a jet fuel starter is being utilized as a power source to drive the accessory equipment when the main jet engines are disconnected from the jet fuel starter, an acceleration and speed control circuit is provided to control a starter clutch that connects the jet fuel starter to the accessory equipment. The acceleration and speed control circuit compares a signal representing a predetermined maximum acceleration and speed with a signal that represents the rate of rotation of the accessory equipment and generates signals to regulate a control valve which in turn controls the starter clutch.
