What information is least likely to be included in a communication transfer?

The choice of aircraft speed as the least likely piece of information included in a communication transfer is based on the standard practices of air traffic communication. In typical communication scenarios, the essential information conveyed during a transfer often focuses on aspects that are crucial for maintaining safety and situational awareness.

Time of communication, fix location, and altitude are all critical for maintaining safe distances, clearances, and overall situational awareness among air traffic controllers and pilots. Time is important for maintaining logs and understanding the sequence of communications. The fix location serves to provide a reference point that enhances navigation, while altitude is vital for vertical separation between aircraft.

Conversely, aircraft speed, while important in the broader context of an aircraft’s operation, is not as commonly included in communication transfers. Speed can be influenced by various factors such as weather conditions and operational procedures, and controllers typically rely on altitude and positioning information for managing traffic more directly. Thus, in the context of a communication transfer, aircraft speed is not generally emphasized, making it the least likely to be included in such communications.
