Which airspace designation is used for a defined purpose and may be designated where flight activity is prohibited?

• A. Short Range Air Defense Engagement Zone
• B. Weapons Engagement Zone
• C. Weapons Free Zone
• D. Special Use Airspace

Answer: (D)

Special Use Airspace is airspace set aside for a defined purpose, where activities require restrictions to protect people and assets. This category covers areas such as prohibited and restricted zones, where flight may be entirely forbidden or limited to certain conditions under authorization. The defining feature is that the airspace serves a specific mission or activity and has the authority to restrict or prohibit flight when needed, which is exactly what the question describes. The other terms aren’t official civil-aviation airspace designations used on charts, so they don’t carry the same established authority to restrict or prohibit flight in a defined area.
