What is typically associated with a Level 2 Caution?

A Level 2 Caution in the A320 is typically indicated by a single chime. This level of caution signifies a situation that requires attention from the flight crew but is not immediately urgent. The single chime serves as an alert without causing excessive alarm, allowing pilots to recognize the need to address the situation while still maintaining focus on their primary tasks.

In contrast, other types of alerts, such as a double chime or continuous buzzer, correspond to different levels of urgency and seriousness. For instance, a double chime generally indicates a more critical situation that may require immediate action, while a continuous buzzer indicates a serious alert that demands immediate attention. A level with no audible notification would indicate that there are no alerts present, which is not applicable to a Level 2 Caution situation. Thus, the single chime is a clear and effective method of notifying the crew of the caution level, allowing for appropriate response.
