Claim:
Control apparatus for an aircraft engine, the control apparatus including: engine control means including: means for receiving a signal representative of a desired thrust for the engine; means for receiving a signal representative of the actual thrust of the engine; and means for analysing the above signals and for producing a signal representative of a desired fuel flow for the engine; and fuel control means including: means for receiving a signal representing a desired fuel flow; means for providing a signal to a fuel monitoring means for regulating the flow of fuel to the engine; means for receiving a feedback signal from the fuel monitoring means; and means for analysing the signal representing desired fuel flow and the feedback signal from the fuel monitoring means and adjusting the signal to the fuel monitoring means for achieving the desired fuel flow; wherein the engine control means and the fuel control means are separately powered such that a failure of the power supply to one of them will not necessarily result in a failure of the power supply to the other.
