What is the recommended method of communication during a security threat?

• A. Disable all radio communications.
• B. Shouting instructions over the intercom.
• C. Maintain open line with the Captain and authorities.
• D. Only communicate with passengers.

Answer: (C)

During a security threat, keeping communication channels open among the flight crew and with external authorities is essential. This ensures information flows accurately, the situation is understood by those who can make decisions, and actions are coordinated through the proper chain of command. Maintaining an open line with the Captain and authorities helps deliver timely updates, receive authoritative guidance, and escalate or adjust response as needed. Disabling all radio communications would cut off those critical links and hinder a coordinated effort. Shouting instructions over the intercom creates chaos and confusion, making it harder to control the situation and keep passengers calm. Limiting communication to only passengers omits vital information that responders rely on, and can delay necessary actions. By staying on designated channels and communicating clearly with the Captain and authorities, the crew can execute a coordinated, effective security response.
