What aviation system is responsible for monitoring and controlling fuel consumption?

The Engine Indicating and Crew Alerting System (EICAS) is specifically designed for monitoring the health and performance of the aircraft's engines, as well as other critical systems, including fuel consumption. EICAS displays real-time information and alerts the flight crew about engine parameters, including fuel flow and usage, ensuring that fuel is consumed efficiently. This allows pilots to make informed decisions during flight operations regarding fuel management.

While the Flight Management System (FMS) plays a role in navigation and flight planning, it includes fuel management functions as part of broader operational considerations; however, EICAS is more directly focused on engine and fuel performance. The Automatic Flight Control System (AFCS) primarily aids in controlling the aircraft's flight path and does not specifically monitor fuel consumption. Integrated Avionics Systems encompass a broader range of functions, but they do not singularly concentrate on fuel monitoring like EICAS does. Understanding the specific function of each system helps clarify why EICAS is the correct choice for monitoring and controlling fuel consumption.
