Which CAS message color represents hazardous conditions that require immediate pilot attention and may require immediate action?

• A. Yellow
• B. Green
• C. Red
• D. White

Answer: (C)

In cockpit alerting, urgency is conveyed by color. Red is used for hazardous conditions that require immediate pilot attention and may call for immediate action. This color stands out and signals a high-priority situation, such as a fire, engine failure, or other critical system malfunction, where quick, organized response is essential.

Green typically means normal operation, yellow indicates a caution or advisory condition that warrants attention but not immediate action, and white is informational or less urgent guidance.
