Patent ID: 8224552

Claim:
A method for assembling a gas turbine engine, said method comprising: coupling a first fuel system interface (FSI-1) to a second fuel system interface (FSI-2); coupling one of the FSI-1 and the FSI-2 to the gas turbine engine; coupling a first control system to the FSI-1 and to the FSI-2, wherein the first control system includes a first driver A and a second driver A; coupling a second control system to the FSI-1 and to the FSI-2, wherein the second control system includes a first driver B and a second driver B; configuring the first control system to apply a first over-speed logic algorithm to determine operation of at least one of the first driver A, the second driver A, the first driver B, and the second driver B, and to apply a second over-speed logic algorithm to determine operation of at least one of the first driver A, the second driver A, the first driver B, and the second driver B, wherein the first over-speed logic algorithm applies different methodologies, calculations, and over-speed thresholds than the second over-speed logic algorithm; and configuring the second control system to apply the first over-speed logic algorithm to determine operation of at least one of the first driver A, the second driver A, the first driver B, and the second driver B, and to apply the second over-speed logic algorithm to determine operation of at least one of the first driver A, the second driver A, the first driver B, and the second driver B.
