What does ATO stand for in the context of air traffic control?

• A. Air Traffic Organization
• B. Air Traffic Services - ATO Service Areas
• C. Air Traffic Administration
• D. Air Transport Office

Answer: (D)

Air Traffic Organization. In the air traffic control context, ATO is the FAA division responsible for delivering air traffic services across the national airspace, including control towers, terminal radar approach control facilities, and en route centers. The acronym reflects the organizational unit, not a specific service area. The other options don’t match the official expansion used in ATC contexts.
