What term describes designated airspace within which flight of aircraft is prohibited?

• A. Restricted area
• B. Prohibited area
• C. Warning area
• D. Military operations area

Answer: (B)

In airspace terms, a Prohibited area is a designated region where flight of aircraft is completely forbidden. These rooms are set aside for security or sensitive activities, and entering without explicit authorization from the controlling authority is not allowed. On charts, you’ll see these areas marked with a P-designation, signaling that no entry is permitted.

That’s why this term is the right choice: it denotes total prohibition, unlike restricted areas where entry can be granted with permission, warning areas which indicate offshore hazards, or MOAs that separate military activity but are not outright off-limits.
