Which control area begins at flight level 270 and extends to FL600?

• A. Arctic Control Area
• B. Southern Control Area
• C. Northern Control Area
• D. Flight Level Zone

Answer: (A)

Upper airspace is organized into control areas with specific vertical boundaries, and some regions have UCAs that start at a particular flight level and extend to another. The Arctic Control Area is defined to begin at Flight Level 270 and continue up to Flight Level 600, providing a dedicated high-altitude region for north-polar traffic with appropriate separation and routing rules. The other regions either have different lower limits or aren’t defined with the same upper extent, and a general term like Flight Level Zone isn’t an official control area designation.
