Which facility is primarily responsible for en-route traffic coordination at high altitude?

• A. Control Tower
• B. Approach Control
• C. Area Control Center
• D. Flight Data Center

Answer: (C)

En-route high-altitude traffic coordination is handled by Area Control Centers. These centers manage the long-range, high-altitude portion of airspace, providing separation, sequencing, and handoffs as aircraft move between sectors and between centers. They coordinate with adjacent centers to maintain a smooth, continuous flow and to ensure safe altitude and speed profiles along routes. The control tower is responsible for airport surface operations and the immediate terminal area, approach control handles arrivals and departures within the terminal area but not the global en-route paths, and a flight data center focuses on flight plan data rather than real-time air traffic control.
