Which acronym is used to refer to airspace related coordination measures?

• A. ACM
• B. ACP
• C. DZ
• D. GMA

Answer: (A)

Airspace coordination measures are the specific actions planners use to synchronize and deconflict airspace during operations. The acronym that refers to these measures is ACM, which stands for Airspace Coordination Measure. These measures set how airspace is shared—timing, locations, altitude bands, and deconfliction rules—so friendly aircraft, support assets, and airspace authorities can operate safely and efficiently together. An Airspace Control Plan outlines how airspace is controlled overall, not the concrete coordination actions themselves; a Drop Zone is simply a landing area for paratroopers, and GMA is not used for airspace coordination measures in this context.
