What does K-66 indicate about handoff status?

K-66 indicates that the handoff has been accepted by the sector, meaning that the receiving controller is ready to take responsibility for the aircraft being handed off. This acceptance is crucial as it confirms that the receiving sector has the necessary resources and situational awareness to manage the incoming aircraft effectively. In air traffic control, a successful handoff is critical for ensuring the safety and efficient movement of aircraft, and K-66 serves as a positive acknowledgment that the process is proceeding as intended.

The other choices do not accurately represent the meaning of K-66. For instance, handoff decline or untracked status would suggest issues or complications in the handoff process, while stating that a track is being handed off does not confirm acceptance by the receiving sector. Thus, understanding K-66 as a sign of acceptance helps clarify communication and coordination in air traffic control operations.
