Which control area is defined as FL180 to FL600?

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

Answer: (B)

High-altitude airspace is organized into controlled regions that manage aircraft as they operate above the standard transition altitude. The range from FL180 up to FL600 defines an upper, controlled block of airspace, and in this regional framework that block falls under the Southern Control Area. That designation reflects which geographic portion is responsible for ATC procedures and separation in this high-altitude band. The other names refer to different geographic regions (or use terminology not applied to this altitude range), so they don’t match the specified vertical limits.
