What flag should be flown when there is a general recall of all personnel?

The flag that indicates a general recall of all personnel is the Papa flag. This flag is part of the International Code of Signals, which is used to communicate specific messages through flags at sea.

The Papa flag, when flown, signifies that all personnel should return to their respective stations or assembly areas. This can be crucial during operations or drills, where quick and coordinated response is necessary for safety and efficiency. Understanding the significance of the Papa flag is essential for maintaining order and ensuring that all personnel are accounted for during various situations.

In contrast to the other flags mentioned, each of which has different meanings in naval signals, the Papa flag specifically conveys the message of recall, making it the correct choice for this situation.
