Which airspace class consists of two circles centered on the primary airport, with the inner circle having a radius of 5 NM?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

The correct answer is Class C airspace. Class C airspace is characterized by its structure that usually consists of a two-layered approach, with an inner circle that extends 5 nautical miles (NM) from the primary airport and an outer circle that ranges out to 10 NM. This design is specifically intended to manage air traffic around busier airports, providing controlled airspace where both VFR (Visual Flight Rules) and IFR (Instrument Flight Rules) traffic can safely operate. Class C airspace is crucial for ensuring the safety of numerous aircraft operating in close proximity to each other around active airports, which often handle a significant volume of traffic. The 5 NM radius around the airport ensures that aircraft can be effectively monitored and instructed by air traffic control as they approach or depart, which is essential for maintaining safe altitudes and separation. In contrast, the other classifications of airspace differ in terms of their structure, regulatory requirements, and intended purposes. Class A is primarily enroute airspace for IFR traffic, Class B airspace encompasses a larger area surrounding major airports with more stringent requirements, and Class D airspace typically represents airports with control towers but doesn’t encompass the same controlled environment as Class C. Each class has specific requirements and functions tailored to
