ICAO-ACC stands for which of the following?

• A. Area Control Center
• B. International Civil Aviation Organization Area Control Center
• C. Interregional Control Center
• D. Airspace Coordination Center

Answer: (A)

Area Control Center is the facility responsible for en-route air traffic control within a defined block of airspace, handling high-altitude and long-range traffic, sequencing and separation, and handing off flights between centers as they progress. That en-route control role is the standard meaning behind ACC in ICAO references, so ICAO-ACC corresponds to Area Control Center. The other phrasings aren’t used as standard ICAO terms for this facility, and adding the International Civil Aviation Organization to the acronym isn’t how the designation is normally written. In many regions you’ll hear the equivalent term used locally, like ARTCC in the US, but ICAO terminology points to Area Control Center.
