What is an example of an appropriate call from an aircraft to a control tower?

The appropriate call from an aircraft to a control tower needs to provide essential details that clarify the identity of the aircraft, its type, and the purpose of the communication in a concise manner. The preferred format typically includes the name of the station being contacted, the aircraft type (or flight number), and the intention (if necessary).

In this instance, the choice that stands out reflects a clear and proper format: it includes the designated radio station, identifies the aircraft with its full name and type, and maintains standard radio communication etiquette with the use of "OVER" to signal the end of the transmission.

The other choices do not adhere to the expected communication protocols as effectively. For example, while one option provides the aircraft’s name and requested action, it lacks the specificity of the communication format typically used in contact with a control tower. Another option uses a generic term, "CONTROL TOWER," which may not be as precise as addressing the specific radio station, thereby making it less effective for a clear and official radio call.
