Which control area stretches from FL230 to FL600?

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

Answer: (B)

High-altitude controlled airspace is organized into areas with specific vertical limits to manage traffic safely at higher speeds and altitudes. The range from Flight Level 230 up to Flight Level 600 defines the upper airspace for that region, which is the Northern Control Area. This designation exists to provide controlled airspace for aircraft operating at high altitudes in northern latitudes where routes and weather patterns require clear separation and consistent procedures. The Arctic Control Area would have a different geographic scope and possibly different vertical limits, the Southern Control Area refers to southern regions with its own limits, and Flight Level Control Area is not a standard regional designation. So the Northern Control Area is the one that matches the FL230 to FL600 band.
