Special interest and CAT track information is provided to RAVC/ADS facilities by which of the following?

The information on special interest and CAT track data is provided to RAVC/ADS facilities through ETMS (Enhanced Traffic Management System) and TSD (Traffic Services Data). These systems are specifically designed to enhance the management and dissemination of flight data, ensuring timely and accurate information is communicated to the relevant facilities.

ETMS helps in tracking air traffic and managing the flow, while TSD focuses on providing essential data that assists in real-time decision-making for air traffic control. Utilizing these systems allows for efficient monitoring and management of airspace, especially for tracks labeled as special interest or involving specific air traffic concerns, such as those requiring additional oversight or identification.

The other options do not primarily encompass the provision of the specialized data in question. Military communication channels are broader in scope and might not focus specifically on the details provided by ETMS and TSD. Local ATC facilities operate mainly within their immediate airspace and might not have the full spectrum of data needed for special interest tracks. National security agencies focus on security matters rather than managing or disseminating air traffic data.
