Definition
An FAA facility that provides air traffic control service to IFR aircraft operating on flight plans within controlled airspace, primarily during the en route phase of flight. Each ARTCC is responsible for a large geographic area of airspace, divided into sectors, and handles aircraft between departure and arrival terminal areas.
Plain English
A regional control facility that watches over and directs IFR aircraft while they are flying between airports, after they leave the departure area and before they reach the arrival area.
Context Anchor
You will encounter ARTCC in radio communication, flight planning, instrument flying, and discussions of who controls an aircraft during the en route portion of a flight.
Derivation
En route' comes from French, meaning 'on the way.' The name reflects the facility's role: controlling traffic on the airways between terminal areas, rather than at the airports themselves.
Why Pilots Care
Provides separation, routing, and traffic advisories for aircraft outside terminal airspace.
Intuition Check
Do not read “Center” as the middle of something. In this term, “Center” means a regional air traffic control facility that manages aircraft across a large area.
Example Sentence 1
After departure, the controller said, 'Contact Kansas City Center on 128.6,' handing the flight off to the ARTCC for the cruise segment.
Example Sentence 2
After climbing out of the departure airport, the flight was handed off to the next ARTCC sector.
