Which airspace requires a pilot to maintain communication with Air Traffic Control?

Class B airspace requires pilots to maintain communication with Air Traffic Control (ATC). This type of airspace surrounds the busiest airports in the United States and is designed to facilitate the movement of a large volume of air traffic while ensuring the safety and efficiency of operations. In Class B airspace, pilots must receive clearance to enter and are required to maintain two-way radio communication with ATC at all times.

Clearance and communication help ensure that aircraft can be managed effectively in a crowded airspace, which includes an array of commercial, general aviation, and other traffic. This is vital for preventing collisions and optimizing the flow of inbound and outbound flights at major airports. Therefore, being in communication with ATC is not just a regulatory requirement but a critical safety measure in managing complex air traffic situations associated with Class B airspace.

While other classes of airspace, like Class A, C, and D, also have communication requirements, the specific nature of Class B airspace emphasizes the importance of explicit clearance and constant communication due to its volume and complexity.
