Which alert indicates a non-critical failure that can be managed normally?

The yellow alert is used to indicate non-critical failures or abnormal conditions that the crew can manage or rectify without immediate action. This alert signifies that while there is a deviation from normal operation, it does not pose an immediate threat to the safety of the flight, allowing pilots to prioritize tasks and address the issue as part of standard operating procedures.

In contrast, red alerts indicate critical malfunctions that require immediate attention and action to ensure safety, while green alerts typically represent normal operational status. Amber alerts are often associated with warnings that may require monitoring but aren't classified as non-critical in the same way. The yellow alert thus plays a crucial role in efficient cockpit management, ensuring that the crew can handle less severe issues while maintaining an overall focus on safety.
