How long does an aircraft lockdown last for Level 1 and Level 2 threats?

The duration of an aircraft lockdown for Level 1 and Level 2 threats is contingent upon the threat subsiding. This means that the safety of the passengers and crew is the primary concern, and the lockdown will continue until there is no longer an immediate danger. For Level 1 and Level 2 threats, which can vary in nature and severity, it is crucial that all necessary precautions are taken to ensure safety, which influences the duration of the lockdown.

In contrast, situations that hinge on the presence of law enforcement or landing the flight may not accurately reflect the immediate circumstances of a threat where waiting for those external factors could delay necessary safety measures. The focus remains on assessing and mitigating the threat directly rather than external conditions. As such, recognizing that the lockdown remains in effect until the threat has definitively subsided is essential for understanding how to protect everyone involved.
