Red colored text on the ECAM screen signifies:

Red colored text on the ECAM (Electronic Centralized Aircraft Monitoring) screen indicates that immediate action is required by the flight crew. This typically signifies a critical malfunction or urgent situation that poses a safety risk to the aircraft or its operation. In such cases, the flight crew must prioritize addressing the issue without delay to ensure the safety of the flight.

The use of red in the ECAM system is a standard color-coded warning protocol, where the color red clearly communicates the severity and urgency of the situation. This allows for quick recognition and response by flight crew members, streamlining their ability to manage emergencies effectively.

In contrast, other colors on the ECAM provide different levels of warning or information: for example, amber generally indicates a caution or alert where immediate corrective action may not be crucial but still requires attention, while green indicates normal operation without the need for corrective measures. Therefore, understanding the implications of red text is vital for maintaining situational awareness and ensuring safety during flight.
