"Air Domain awareness is the effective understanding of threats associated with the Air Domain that could impact the security, safety, or economy of the United States. Achieving such understanding requires close coordination across the United States Government to better integrate intelligence, information, and surveillance data, and analysis related to the Air Domain to facilitate a shared situational awareness across Federal, State, local, and tribal governments and private entities and foreign partners that have aviation security responsibilities. This Air Domain awareness supports a multitude of users across the full spectrum of aviation security and defense activities, including the prevention, response, and recovery activities described in the Aviation Transportation System Security, Aviation Operational Threat Response, and Aviation Transportation System Recovery plans. […] This Plan is an overarching U.S. Government plan that supports and enables the successful execution of the aviation security plans developed pursuant to NSPD-47/HSPD-16. This Plan serves to enhance the U.S. Government's capacity to possess effective knowledge of the threats to the United States and U.S. interests in the Air Domain, including the ability to detect and collect information on aviation threats, integrate and analyze that data in conjunction with associated intelligence information, and disseminate the resulting understanding to deter, prevent, and respond to attacks on the United States or its interests."
