When must Security Directives be implemented?

Security Directives must be implemented immediately unless otherwise stated because they are issued to address urgent security concerns that arise within the aviation sector. The nature of these directives is to provide prompt guidance or actions required to mitigate potential threats and enhance security measures swiftly.

In many instances, delaying the implementation of these directives could expose passengers and the aviation system to unnecessary risks. Therefore, a sense of urgency is inherent in the nature of Security Directives, which sets them apart from other guidelines that may allow for a more gradual or consultative approach. The immediate enforcement ensures that the highest level of security is maintained consistently, regardless of the circumstances surrounding their issuance.
