What color indicates EICAS engine limits?

The color that indicates EICAS (Engine Indication and Crew Alerting System) engine limits is red. This color is universally recognized in aviation as a signal for warnings or conditions that require immediate attention. When values displayed in EICAS turn red, it indicates that they are outside of acceptable operating limits, which could potentially lead to a safety hazard or engine damage. This visual cue is critical for pilots, allowing them to quickly identify and address serious issues that may arise during flight operations.

Understanding the significance of colors in EICAS is vital for maintaining situational awareness and ensuring safe operations, as it helps communicate the status of various engine parameters instantly.
