Which facility provides en route ATC services and separation for high-altitude air traffic?

• A. Air Route Surveillance Radar
• B. TRACON
• C. Air Route Traffic Control Center
• D. Flight Service Station

Answer: (C)

En route ATC services and separation for high-altitude traffic are provided by the Air Route Traffic Control Center. These centers manage aircraft as they fly long distances between airports, maintaining safe separation, assigning altitudes, and coordinating handoffs between centers and with approach control as needed. They cover the high-altitude en route airspace, which is different from the terminal area around airports.

TRACON handles approach and departure traffic near airports, not en route separation. Flight Service Station offers pilot weather briefings and flight planning rather than air traffic control separation. Air Route Surveillance Radar is a radar system used by the centers to track aircraft, not a separate operating facility.
