Which document designates airspace control sectors and contains deconfliction information?

• A. DIMS
• B. SPINS
• C. ACO
• D. ATO

Answer: (C)

The concept being tested is which document actually sets up the airspace control picture by naming the sectors and laying out deconfliction instructions. The Airspace Control Order is the one that publishes the boundaries of each airspace control sector, designates which authority controls which sector, and includes the deconfliction measures needed to prevent conflicts between airspace users. It provides the concrete, sector-by-sector view that controllers rely on to apply airspace control.

General instructions for airspace control, such as SPINS, guide how the control measures are implemented but don’t define the sector boundaries themselves. The Air Tasking Order focuses on assigning missions and which assets operate where and when, not on delineating the physical sectors or detailing deconfliction between sectors. DIMS isn’t the standard publication for publishing sector boundaries either.
