Level 4 Security Threat is defined as which of the following?

• A. Attempted or actual breach of flight deck
• B. Weapons displayed/used
• C. Verbal harassment
• D. Physically abusive behavior

Answer: (A)

Level 4 security threat centers on protecting the flight deck. It is defined as an attempted or actual breach of the flight deck, meaning someone tries to force entry into the cockpit or actually gains access. This situation directly endangers the crew and the flight, so the on-board security response is the highest priority, with coordination to authorities as needed. While weapons displayed or used or other disruptive behaviors are serious and may trigger security actions, the defining trigger for Level 4 is the breach attempt or actual breach of the flight deck. Verbal harassment and physically abusive behavior are disruptive and serious, but they do not, by themselves, define Level 4, since the critical factor here is the threat to or breach of the cockpit.
