Which sign indicates that entry to an airspace is prohibited?

• A. A runway assignment sign
• B. A traffic pattern entry sign
• C. A 'No Entry' sign
• D. An airport amenities sign

Answer: (C)

A 'No Entry' sign clearly indicates that entry into a specific airspace is prohibited. This type of sign serves as an explicit directive to pilots, ensuring they understand that they cannot proceed into the designated area for safety reasons or regulatory compliance. The 'No Entry' sign is typically used in situations where certain airspace is restricted to protect persons, property, or to maintain the safety of operations. In contrast, other signage options, such as a runway assignment sign, primarily provide information about specific runways designated for arrivals or departures, but do not indicate restrictions on entry. A traffic pattern entry sign informs pilots of the standard traffic pattern but does not prohibit entry into the airspace. Similarly, an airport amenities sign highlights available services or facilities at the airport but does not pertain to restrictions on airspace entry. Thus, the role of each sign differs significantly, with the 'No Entry' sign serving as a clear and direct communication of prohibited access.
