What decision must be made regarding the PA system for a flight?

The requirement for the PA system to be repaired if faulty stems from its critical role in communicating important information to passengers and crew members during a flight. The PA system is essential for announcing safety instructions, flight information, and any emergency procedures that may need to be conveyed. If the system does not function properly, there could be significant risks to safety and situational awareness among passengers and crew.

Regardless of whether the flight is domestic or international, the PA system is an integral part of flight operations and contributes to the overall safety and efficiency of the flight. Therefore, maintaining the reliability of this system is necessary and ensures that all operational protocols can be followed, particularly during emergencies.

The other choices do not accurately reflect the importance of the PA system in aviation safety and communication protocols.
