The statement 'Entry is limited' refers to which type of area?

• A. Restricted areas
• B. Public areas
• C. Restricted zones
• D. Controlled areas

Answer: (D)

Airspace is divided into sections with different access rules, and the phrase “Entry is limited” signals that access isn’t open to everyone but is controlled by authorities. This matches controlled areas, where entry is managed and pilots must obtain clearance and follow specific procedures to enter. Public areas are open and unrestricted, so entry isn’t limited. Restricted areas (or restricted zones) imply a prohibition or severe restriction without explicit permission. The idea of limited entry fits the idea of ATC-controlled airspace where access is regulated rather than fully prohibited or entirely open.
