During pre-departure, what needs to be made aware of armed passengers?

The most appropriate action regarding armed passengers during pre-departure is to make other armed passengers aware of each other. This communication is crucial for safety and coordination among individuals who are carrying arms. By ensuring that armed passengers know who else is armed on the flight, it helps in managing any potential security risks and fostering an environment where all individuals can operate with knowledge of one another.

Awareness among armed passengers can reduce the chances of misunderstandings or misinterpretations of actions during the flight that might lead to alarm or panic, enhancing overall safety onboard. While informing crew members and the flight operations team is important for overall flight safety and security, the immediate concern focuses on the interaction and potential dynamics between the armed passengers themselves.
