Definition
A formal notification issued when a charted obstruction, construction project, or airspace change has been completed and the temporary advisory or NOTAM associated with it can be removed or updated. It signals that the affected feature is now in its final, charted state.
Plain English
A message saying 'this work is done' so that any temporary warnings about it can be retired and the charts can be trusted again.
Context Anchor
Seen in FAA acronym and NOTAM-contraction lists, and in records connected with airport work, airspace changes, or other reported aviation activities.
Why Pilots Care
Pilots use this information to confirm when previously closed runways, taxiways, or facilities are available again so they can plan safe operations.
Intuition Check
Do not read this as just a casual message that something is done. In this context, it is an official notice used to update or close an aviation record.
Example Sentence 1
After the new tower was built and surveyed, the FAA issued a notice of completion (NOC) so the obstacle could be added to the sectional chart.
Example Sentence 2
After reviewing the NOC, the flight crew proceeded with departure knowing the affected taxiway was open.
