What are the two major components of a supervisory electronics engine control?

The correct answer identifies the electronic control unit and the hydro-mechanical fuel control as the two major components of a supervisory electronics engine control system. The electronic control unit (ECU) plays a vital role in managing engine performance by processing input from various sensors and making real-time adjustments to optimize fuel flow and other engine parameters. This unit utilizes advanced algorithms to control various systems for peak efficiency and performance.

The hydro-mechanical fuel control works in conjunction with the ECU to manage the fuel flow to the engine, ensuring that the fuel-air mixture is optimal for various operating conditions. It provides a reliable, backup mechanical function that operates alongside the electronic systems, enhancing redundancy and safety in engine operation.

This combination allows for precise engine control while maintaining reliability, which is critical for modern aircraft engines. The other options listed do not accurately represent the core components of such a supervisory control system, as they either incorporate irrelevant elements or do not reflect the fundamental dual-component structure that integrates both electronic and mechanical systems.
