Abstract
An improved back-up control for use in an aircraft gas turbine engine is presented and includes a fuel control valve adapted to meter the flow of fluid to the gas turbine engine, first means for providing a mechanical position signal indicative of the magnitude of a desired fuel flow change to the engine and second means for limiting the rate at which a change in the signal is transmitted to the fuel control valve thereby limiting the rate of change in fuel flow to the engine. The second means may limit the transmission rate in response to inlet pressure. A variable geometry control valve is provided for varying the position of the variable elements of the gas turbine engine in response to said mechanical position signal and the second means limits the rate at which a change in the signal is received by the variable geometry control valve.
