What color in the ECAM indicates a configuration or a failure that requires immediate correction?

In the A320's ECAM (Electronic Centralized Aircraft Monitor), red is the color that signifies a condition requiring immediate action or correction. This is critical for pilots, as it alerts them to serious failures or hazardous situations that could compromise the safety of the flight. When a red indication appears, it typically means that the issue must be addressed without delay to ensure the aircraft's safe operation.

For example, a red warning can indicate a system failure such as an engine fire or a critical system malfunction that could lead to severe consequences if not resolved quickly. The urgency conveyed by the red color supports pilots in prioritizing their response during high-stress situations.

In contrast, other colors serve different purposes: green indicates normal operations, blue signifies selected configurations or information that do not require immediate action, and yellow is used for caution items, primarily indicating a condition that is not critical but still requires attention.
