What does the acronym ACO stand for?

• A. Airspace Control Office
• B. Airspace Control Order
• C. Airspace Coordination Order
• D. Air Control Operations

Answer: (B)

In airspace management, the term you use to implement how airspace is controlled is Airspace Control Order. This directive translates the airspace control plan into actionable measures, specifying which parts of airspace are active, what operations are allowed, and who has authority over different sectors and times. It’s issued by the Airspace Control Authority and used by controllers and airspace users to keep operations deconflicted and safe as the battlespace evolves. The other options refer to a type of office, a different kind of order, or a general operation, none of which capture the formal term used to execute airspace control.
