The paper describes the architecture and construction of the system being applied to the Pegasus engine and aimed at the AV8B application. The systems architecture was particularly determined by the requirements of a single engined VSTOL aircraft. It is essentially a dual-dual system. Theis architecture was chosen to provide reliable and positive detection of failure with rapid reaction and no degradation of performance. The paper discusses the likely extension of this system to the control of plenum chamber burning PCB. The system includes a data bus terminal in each lane of the system. This provides communication path between the engine control and EMC system in the aircraft. A similar terminal could provide a path through which the operation of the flight control, the weapon control and the engine control systems could be integrated. This integration is required because of interaction between the operation of the engine and the release weapons, the attitude of the aircraft and the mechanics of these interactions and the principles employed in the mitigation of their effects.
