Airspace Coordination Area (ACA) is defined as what?

Airspace Coordination Area (ACA) is defined as what?

• A. ACA stands for Air Control Area, a two-dimensional shape.
• B. Airspace Coordination Area is a three-dimensional block of airspace established by military authorities to coordinate and regulate usage.
• C. ACA is a no-fly zone for civil traffic.
• D. ACA is a data link standard.

Answer: (B)

A three-dimensional block of airspace established by military authorities to coordinate and regulate usage. The key idea is that airspace isn’t just a flat area; it has vertical limits as well, and this designated volume allows both civil and military traffic to operate safely with agreed procedures for separation and coordination. It’s not simply a no-fly zone or a data link standard, and it isn’t just a two-dimensional shape—the ACA defines a 3D space for controlled, coordinated use.
