Which type of communication must VFR aircraft maintain in Class B airspace?

In Class B airspace, VFR (Visual Flight Rules) aircraft are required to maintain two-way communication with Air Traffic Control (ATC) on the assigned frequency. This requirement is critical for ensuring safety and efficiency in a busy airspace environment, where many aircraft operate in close proximity. By having two-way communication, pilots can receive essential traffic advisories, instructions for safe flying, and any necessary clearances that may help to avoid conflicts with other aircraft.

This type of communication allows both the pilot and ATC to actively engage in dialogue about flight conditions, routing, and traffic, which is essential in an airspace primarily designed to manage higher volumes of traffic, especially around major airports. The requirement for communication is specific and must be conducted on the frequency assigned to the aircraft by the ATC, ensuring that all parties are on the same page and enhancing overall situational awareness.

Options like one-way radio communication do not meet the requirements necessary for safe operations in Class B airspace, as there would be no ability to receive instructions or respond to traffic advisories. Similarly, two-way communication on any frequency lacks the specificity needed to maintain an organized flow of communication, which is vital in such high-traffic environments. Emergency communication only is insufficient as it
