Under nonradar procedures, when does Aero ARTCC assume responsibility for control of air traffic?

Aero ARTCC assumes responsibility for control of air traffic at and above 6,000 feet in nonradar procedures. This altitude is significant because it typically represents the point where aircraft are higher than most terrain and obstacles, allowing for more efficient vertical separation between aircraft. At this altitude, controllers can manage air traffic more effectively due to established airways and routing protocols that are designed for higher altitude operations.

In many regions and under various regulatory frameworks, the altitude thresholds for air traffic control responsibilities vary, but the general guideline indicates that above 6,000 feet, ARTCC can implement procedural separation standards and track aircraft as they transition to higher altitudes, ensuring safety and efficiency in air traffic management. This also aligns with the national airspace system protocols, providing a structured way of integrating aircraft into controlled airspace.
