Aero ARTCC assumes control of air traffic when?

Aero ARTCC assumes control of air traffic when the ATCT radar is out of service because the reliability of radar data is essential for safe air traffic management. In situations where the ATCT (Air Traffic Control Tower) loses radar functionality, it is unable to adequately monitor and manage aircraft in its controlled airspace. Transferring control to the ARTCC (Air Route Traffic Control Center) ensures that air traffic continues to be managed effectively, utilizing broader radar coverage and more extensive resources available at the ARTCC level.

In contrast, the other circumstances do not necessarily trigger a transfer of responsibility. When ATCT radar is operational, it typically retains air traffic management responsibility. Emergencies can involve various protocols but do not automatically mean that ARTCC will take over unless specific conditions warrant it. Peak traffic times do not lead to a standard transfer of control; instead, the existing ATCT is expected to manage these situations.
