When must point out and sector number coding in the ACL be deleted?

The requirement to delete point out and sector number coding in the Aircraft Control Log (ACL) once the coordination is complete is based on the efficiency and clarity of air traffic control procedures. This step ensures that the workflow remains organized and that the information being used is pertinent to current operations.

Keeping coding after coordination could lead to confusion, as it may imply that old information is still relevant when it is not. By removing these codes once coordination is complete, controllers are signaling that the team is clear on the handoff or transfer of responsibility for the aircraft. This practice helps maintain an accurate and updated log, preventing any potential mix-ups or miscommunications regarding aircraft positions and status during active operations.

Other options, although they relate to different operational processes, do not align with the specific timing for deletion of the point out and sector number coding concerning coordination status.
