ABSTRACT:
A fuel control system for a gas turbine engine has a pump which delivers fuel to a supply passage. A spill valve downstream of the pump is responsive to a servo pressure signal to spill fuel from the supply passage. A pilot valve is controlled by a torque motor to regulate the servo pressure signal. The torque motor is responsive to an electrical signal dependent on a difference between desired and actual engine speeds.
