ABSTRACT:
An improved integrated control system for a gas turbine engine includes fuel control means for metering the flow of fuel to the engine in accordance with a fuel control position signal. A primary control means generates a primary fuel control position signal. A back-up control means generates a back-up fuel control position signal as a function of the actual engine speed in a primary mode and as a function of the power lever angle in a back-up mode. Transfer means is included to receive both the primary and back-up fuel control position signals and to provide only the primary signal to the fuel control means when the system in the primary mode and to provide only the back-up signal to the fuel control means when the system is in the back-up mode.
