In a Full Data Block, which data element is required to identify the aircraft?

• A. Aircraft Identification
• B. Flight Plan
• C. Altitude
• D. Call Sign

Answer: (D)

In a Full Data Block, the Call Sign is the identifier used to recognize the aircraft. This field carries the textual label assigned to the aircraft and is the reference ATC uses to distinguish one target from another on the radar display. Other data elements, like altitude or flight plan, describe the aircraft’s state or planned route but do not uniquely identify the aircraft themselves. Therefore, the Call Sign is the element that identifies the aircraft in the data block.
