What elements are used by MFC for fuel scheduling?

The correct answer highlights the specific elements utilized by the Maintenance and Fuel Control (MFC) system for efficient fuel scheduling. The combination of CIT (Control Indicating Transmitter), CDP (Compressor Discharge Pressure), and Ngg (normalized gas generator speed) plays a critical role in determining the fuel flow based on operational needs and engine performance.

CIT provides real-time data on engine parameters that are crucial in maintaining optimal conditions, while CDP gives insight into the compressor's efficiency and operational capacity. Ngg reflects the performance and operational speed of the gas generator, which must be finely tuned to ensure accurate fuel measurement and scheduling.

Together, these components allow for precise control of the fuel flow, ensuring efficient fuel management that aligns with the power requirements of the gas turbine. Understanding how these elements interact within the MFC framework is essential for effective gas turbine operation and maintenance.
