Fire Support Coordination Measures 30 April 2020 FM 3-09 B-23 B-80. A formal airspace coordination area is graphically shown (see figure B-20) as an area enclosed by a solid black line. Depicted inside the enclosed area are "ACA," the establishing HQ, the minimum and maximum altitudes, the grid coordinates for each end of the baseline and the width of the airspace coordination area, the grid coordinates for each point of an irregularly shaped airspace coordination area, and the effective date-time group or the words "on-order." Informal airspace coordination areas are not normally displayed on maps, charts, or overlays.

Figure B-20. Airspace coordination area example Note: The depiction of airspace coordination area on a two-dimensional surface such as on a map does not display the possibly irregularly shaped airspace coordination area dimensions (such as Army Tactical Missile System (ATACMS) missile or Excalibur flight paths) that may be constructed within automation systems, which can provide information for airspace clearance.
