In EICAS terminology, which color is used to indicate warnings?

• A. Green
• B. Blue
• C. Red
• D. Amber

Answer: (C)

Red signals warnings. This color is reserved for urgent or critical conditions that require immediate crew action, helping you spot the most severe issues at a glance. It stands out from the others to prioritize safety: amber indicates cautions that should be monitored or corrected but aren’t immediately dangerous, blue conveys information or advisories, and green shows normal operation. For example, a failing engine or an engine fire would trigger red warnings, prompting you to follow the corresponding checklists and take prompt corrective steps.
