What do National Security Areas (NSAs) consist of?

National Security Areas (NSAs) consist of airspace with defined vertical and lateral dimensions that require special attention for national security purposes. These areas are established to protect sensitive facilities and operations from potential threats, and during times of heightened security, pilots are strongly advised to avoid flying through them.

The designation of NSAs is important for maintaining overall security and helps ensure that operations related to national security are conducted safely and without interference from general aviation traffic. While other terms may relate to types of airspace or restrictions, the defining feature of NSAs is their specific dimensions and the clear objective of protecting national security assets.
