What behavior qualifies as a Level 1 threat?

A Level 1 threat typically refers to behavior that can disrupt safety and security on board an aircraft but does not pose an immediate risk of harm. Repeated non-compliance with crew instructions is a clear indicator of such a threat because it reflects a passenger's refusal to follow established safety protocols, potentially endangering themselves and others. This kind of behavior can escalate tensions and creates an environment where the crew's ability to manage the situation effectively is compromised.

In contrast, behaviors that involve calm conversation, proactive engagement with emergency procedures, or polite discussions don't signal a threat to safety or compliance with regulations. These behaviors indicate an understanding of the situation and a willingness to cooperate with the crew, which is crucial in maintaining a safe and secure environment onboard.
