ACA stands for which term in airspace management?

• A. Airspace Control Area
• B. Airspace Allocation Area
• C. Airspace Coordination Area
• D. Airspace Management Area

Answer: (C)

Airspace Coordination Area emphasizes the coordination and deconfliction processes that are essential when multiple users share the same airspace. In airspace management, this term designates the area where planners, controllers, and operators align procedures, routes, altitudes, and restrictions so movements don’t clash and operations run smoothly. That focus on coordinating actions across different actors is what makes it the best fit.

The other concepts describe different roles: one refers to a formal controlled airspace with authority to provide separation and clearance, not the coordination process itself; the remaining terms aren’t standard descriptors for this function. So the term that centers on coordinating use of airspace is the correct choice.
