2. 70

3. 80

4. 90

The correct answer is: 90

The subject number associated with FAA advisory circulars focused on air traffic control is indeed 90. This designation covers the regulations and guidance pertaining to the operation of air traffic services and the role of air traffic controllers in ensuring safe and efficient air traffic management. Understanding the context of this subject number is crucial for those in aviation. Advisory circulars under this number provide essential information that includes operational procedures, communications, and more, which are vital for pilots and air traffic personnel alike. These documents help in maintaining safety standards and in informing stakeholders about updates or changes in air traffic control procedures. The other subject numbers pertain to different areas within aviation regulation: for example, subject number 60 deals with airman training and testing, while 70 focuses on airspace and air traffic management in a broader sense than just the operational instructions encapsulated in advisory circulars. Therefore, recognizing that 90 is specifically geared towards the air traffic control domain helps clarify its unique role within FAA advisory materials.
