When are two-way radio communications with Air Traffic Control required?

Two-way radio communications with Air Traffic Control are required at all tower-controlled airports regardless of weather conditions because these airports have established procedures and protocols that necessitate constant communication between pilots and air traffic controllers to ensure safe and efficient operations. The requirement for communication does not hinge on the weather; rather, it is essential for managing aircraft movements on the ground and in the airspace surrounding the airport.

At tower-controlled airports, ATC is responsible for providing instructions, clearances, and traffic advisories to ensure the safety of all aircraft operating in that environment. This constant communication helps in avoiding collisions, managing departures and arrivals, and maintaining the orderly flow of air traffic in and around busy airspaces. Thus, the expectation for two-way communication is a fundamental aspect of operating within a controlled airport environment, which underscores the commitment to safety and efficiency in aviation operations.
