🔍 Key Concepts

• How the main fuel control in a gas turbine coordinates both fuel flow and variable stator vane (VSV) position • The difference between acceleration schedule and deceleration schedule in fuel control logic • What components in the diagram are grouped inside the dashed box labeled Fuel Control and what they connect to

💭 Think About

• Look at every line leaving the fuel control box: what systems or components is the fuel control influencing? • Which devices or schedules must be managed to prevent compressor stall or flameout during rapid speed changes? • Does safe turbine operation during both power increase and power decrease require one, two, or all of the listed functions to be coordinated?

✅ Before You Answer

• Trace the line from fuel control to the pressurizing valve and then to the fuel nozzles – what schedule(s) does that imply? • Trace the line from fuel control to the variable stator servo/actuators – what function on the answer list matches that path? • Ask yourself whether the main fuel control would logically handle only one of these functions, or must coordinate all related fuel and vane actions for smooth turbine operation
