What is the meaning of an amber CAS message?

An amber CAS message serves to alert the flight crew to a situation that requires attention, although it does not necessarily demand immediate action. These messages are designed to highlight potential issues that could affect the aircraft's performance or safety, thereby allowing the crew to assess the situation and decide on a course of action at an appropriate time. Though these alerts should not be ignored, they indicate that the situation is not immediately dire, providing the crew with time to evaluate and respond effectively based on the context and operational priorities.

In contrast, messages categorized as information only do not indicate any issues or require any follow-up, while those that signal critical failures demand urgent attention and immediate corrective action. Operator awareness messages could provide context or reminders but do not typically fall within the same urgency as amber CAS messages.
