Abstract

The system includes a main fuel flow scheduling means, an auxiliary fuel flow scheduling means, a power demand adjuster operative to adjust both scheduling means, and a failure detector capable of detecting failure of the main scheduling means and of making the auxiliary scheduling means operative to control fuel flow to the engine following such failure. In one arrangement, an adjustment means is connected with the auxiliary scheduling means 201, 246, 209, 221, 222, 231, 232, 233, 234 for continuous adjustment by the flow to the engine permitted by the main scheduling means 184 whereby to ensure that whenever the auxiliary scheduling means begins to control fuel flow, the flow remains constant at the instant of changeover. The auxiliary scheduling means may be arranged for slow self-variation after the changeover to alter the relation between fuel flow to the engine and the setting of the power demand adjuster. The fuel flow may be adjusted in response to engine speed, inlet temperature or pressure by a spill valve, a variable displacement pump or a fixed displacement pump drivable at variable speed under electrical control. <IMAGE>
