What does the EICAS priority display first?

The EICAS (Engine Indication and Crew Alerting System) priority display is designed to convey critical information to the flight crew in a prioritized manner. The system highlights warnings as the most urgent notifications, which are represented in red. This priority is essential because warnings indicate immediate and hazardous conditions that require the crew's attention and action to ensure safety.

In the context of flight operations, warnings can pertain to critical issues such as an engine failure, loss of cabin pressure, or other serious malfunctions. Their red designation ensures they stand out, allowing the crew to prioritize their response accordingly.

The other categories—caution, advisory, and status—are represented in amber, green, and white, respectively, and denote progressively less critical situations. While these alerts are significant, they do not require immediate action as warnings do, emphasizing the necessity for the EICAS to prioritize warnings first for optimal safety and situational awareness.
