Which level of priority involves the Master WARN light flashing?

The Master WARN light flashing is indicative of a Level 3 priority issue. This priority level is used to alert the flight crew to a condition that requires immediate attention but does not pose an immediate threat to flight safety. Level 3 warnings typically relate to non-critical system failures that, while serious, still allow for the aircraft to be operated normally until the next safe opportunity to address the issue arises.

Understanding the priority levels is essential for effective crew resource management and flight safety, as it helps crew members prioritize their actions and responses to various alerts during flight operations. Level 1 issues, for instance, represent immediate threats that require urgent action, making it crucial for pilots to recognize the distinction in order to manage aircraft systems effectively.
