When will CAS messages remain displayed?

The correct answer indicates that CAS messages will remain displayed until the associated condition is resolved. This is a key feature of the CAS (Crew Alerting System) that helps ensure pilots are aware of and can address any issues that may arise during flight. The purpose of the system is to provide timely alerts about abnormal situations or malfunctions, and retaining the message until the condition is resolved emphasizes the importance of addressing these issues promptly to maintain safety.

The other choices do not accurately capture how the system functions. For instance, displaying messages until the next flight would be impractical because it could lead to confusion and information overload from past conditions that might not be relevant. Saying the messages display for a fixed duration of 30 seconds overlooks the dynamic nature of the CAS, which is designed to persist in alerting pilots as long as a condition is present. Lastly, while some systems may allow for manual clearing, the CAS is intended to automatically manage alerts based on the status of the aircraft, ensuring pilots focus on current issues rather than having to remember to clear notifications themselves.
