What key factor distinguishes Class B airspace from Class C airspace?

• A. Class B airspace has a lower altitude limit
• B. Class B airspace requires a two-way radio communication with ATC
• C. Class B airspace is uncontrolled
• D. Class B airspace is reserved for military operations

Answer: (B)

The defining characteristic of Class B airspace is that it requires two-way radio communication with air traffic control (ATC) to operate within its boundaries. This means that before entering Class B airspace, pilots must establish and maintain communication with ATC, ensuring a structured and safe environment for both commercial and private aircraft. This communication requirement is crucial due to the high volume of air traffic often found within Class B airspace, typically surrounding major airports, which helps in managing the traffic efficiently and safely. In contrast, while Class C airspace also requires two-way radio communication, the overall structures and purposes of Class B and Class C airspaces differ significantly. Class B airspace is designed to handle more complex traffic with stricter communication protocols, whereas Class C airspace, while still busy, has a slightly different operational approach focused on smaller airports. The other options do not accurately capture the distinguishing features of Class B airspace. For instance, Class B does not necessarily have a lower altitude limit compared to Class C; instead, it often extends to higher altitudes. Class B airspace is controlled airspace, not uncontrolled as one might infer from some of the other options. Lastly, Class B airspace is not reserved solely for military operations, as it
