What should you do when communicating with an aircraft on initial contact?

When communicating with an aircraft on initial contact, clearly stating the aircraft's identification is crucial for several reasons. It allows both the pilot and the air traffic controller (ATC) to establish a common frame of reference and ensures that the communication is directed to the correct aircraft. Proper identification aids in reducing confusion and enhances safety, as it confirms to both parties that they are engaged in the correct dialogue.

Additionally, stating the identification helps to build a record of the communication, which is important for tracking and situational awareness. It sets the stage for any further communication and instructions, making it foundational in the ATC process.

Other choices may involve relevant information in specific situations, but they do not serve the primary purpose of initial contact as effectively as stating the aircraft's identification does. For instance, asking for a destination or altimeter setting comes later in the sequence of communication and assumes prior verification of which aircraft is being addressed. Stating the identification first ensures that any critical information exchanged afterward is accurate and relevant to the correct aircraft.
