What is the purpose of the Engine Indication and Crew Alerting System (EICAS)?

The Engine Indication and Crew Alerting System (EICAS) plays a crucial role in the aircraft's operation by displaying vital engine parameters and providing alerts for any malfunctions. This system enhances situational awareness for the flight crew by continuously monitoring the performance and status of the engines. It presents data such as engine temperature, pressure, and other critical indicators, allowing pilots to manage engine performance effectively and address issues promptly.

By ensuring that pilots have access to essential information about engine performance, especially in abnormal situations, EICAS facilitates timely decision-making and enhances flight safety. Without such a system, the flight crew would be less aware of the current status of the engines, which could lead to delays in addressing potential mechanical issues.

In contrast, the other options focus on different functions that do not align with the primary responsibilities of EICAS. For instance, controlling fuel distribution, monitoring cabin pressurization, and operating navigation displays are managed by separate systems in the aircraft's avionics suite.
