An electronic fuel control system for varying the fuel flow to a gas turbine engine during the engine\s acceleration. The reference speed set point of the engine\s fuel controlling governor is increased as a function of the elapsed time from engine start-up and the engine characteristics so that the engine accelerates substantially along its “required to run line.

A system for controlling fuel flow in a gas turbine engine, comprising: timing means for generating a time signal indicative of the elapsed time from engine start-up; means for sensing engine speed; means responsive to said timing means and to the sensed engine speed for scheduling a rate of fuel flow as a function of the time signal; means for producing an error signal when the rate of fuel flow to the gas turbine engine exceeds a predetermined rate for the sensed engine speed; and means for inhibiting said timing means in response to said error signal to maintain the fuel flow rate to said predetermined schedule corresponding to the sensed engine speed.
