What is the correct sequence for interphone communication between controllers?

The correct sequence for interphone communication between controllers is to first identify the facilities involved. This is important because it establishes the context of the communication, ensuring that the receiving controller knows from whom they are receiving the information and can understand the operational environment. After identifying the facilities, the next step is to state the message clearly. This allows the recipient to grasp the pertinent information being conveyed without confusion or ambiguity. Finally, giving initials helps confirm the identity of the person communicating, which is critical for maintaining accountability and clarity in air traffic control communications.

This structured approach enhances the effectiveness of communications, reducing the risk of misunderstandings that could impact safety and efficiency within air traffic operations. By following this sequence, controllers can ensure that their messages are delivered in a clear and organized manner, which is essential in the fast-paced and high-stakes environment of air traffic control.
