Air Route Traffic Control Centers (ARTCCs) primarily communicate with pilots using radio communication because this method provides a reliable and effective means of transmitting real-time information and instructions over long distances. Radio communication allows for immediate two-way interaction, enabling air traffic controllers to give pilots critical updates, clearances, and instructions regarding flight paths, altitude adjustments, and other essential operational details.

This method is essential for maintaining safety and efficiency in the national airspace system, as it allows for quick responses to dynamic conditions during a flight. The use of specific frequencies allocated for aviation ensures that communication is clear and understood, minimizing the risk of miscommunication, which can occur with other methods. Structured protocols in radio communication, such as phraseology and standard responses, further enhance clarity.

Other options, such as in-flight security teams, visual signals, or written instructions, fall short in meeting the demands of real-time air traffic management. In-flight security teams are not primarily responsible for regular communication between pilots and air traffic control. Visual signals can be used in limited ground operations or during specific situations but are not practical for communication at cruising altitudes. Written instructions could not provide the immediacy required for ongoing air traffic communication, making them inappropriate for real-time pilot-controller interactions.
