Abstract
A method for selecting a setpoint for a turbofan engine having a fan speed and a core idle speed scheduling includes determining a weighting factor based upon a throttle lever position, the weighting factor being zero in an idle region and ranging from zero to one in a dead band region and applying the weighting factor to an output of a fan speed governor and to an output of a core speed governor to select the setpoint.
