What must the flight attendant do if they notice any issues during the checks?

The flight attendant must notify the Captain immediately if they notice any issues during the checks. This is crucial for maintaining safety and ensuring that any identified problems are addressed without delay. The Captain has the ultimate authority and responsibility for the flight, including the safety of passengers and crew. By promptly informing the Captain, the flight attendant ensures that appropriate actions can be taken to resolve the issue, whether it involves adjusting procedures, returning to the gate, or conducting further safety checks.

Immediate reporting is essential in the context of Crew Resource Management, which emphasizes effective communication and teamwork in addressing safety concerns. Understanding that any issue, no matter how minor it may seem, could have implications for the safety of the flight reinforces the importance of this protocol. The focus is always on proactive safety measures rather than reactive or neglectful behaviors, which would undermine the principles of effective safety management in aviation.
