What is the purpose of the No Entry sign?

• A. Identifies a paved area where aircraft are prohibited from entering.
• B. Indicates a taxiway exit only
• C. Indicates the runway edge
• D. Indicates a parking area

Answer: (A)

On the airfield, signs guide where you may move. The No Entry sign is a red circle with a white horizontal bar. Its purpose is to indicate that the area beyond the sign is off-limits to aircraft. It marks a paved area where entry is prohibited to prevent you from taxiing into a restricted zone, work area, or other unsafe space. It’s not indicating a taxiway exit, the runway edge, or a parking area—the No Entry sign is specifically about prohibiting access. If you see it, do not enter; stop and follow ATC directions or taxi to a permitted route.
