Abstract
A system includes a burn flow line and a flow divider valve in fluid communication with the burn flow line to split flow from the burn flow line to a primary line and to a secondary line for supplying fuel to a set of primary engine nozzles and to a set of secondary engine nozzles, respectively. A sensor operatively connected to the flow divider valve to produce a feedback signal indicative of flow split between the primary line and the secondary line. A controller is operatively connected to receive the feedback signal from the senor, compare the feedback signal to a stored flow split value for a mismatch, and output an alert message upon detecting the mismatch.
