When can ATC issue a STAR to a pilot?

ATC can issue a Standard Terminal Arrival Route (STAR) to a pilot when they deem it appropriate for managing traffic and maintaining an orderly flow into terminal areas. This means that ATC assesses the current air traffic situation, weather conditions, and overall operational requirements to decide whether a STAR is beneficial for the flight, enhancing both safety and efficiency.

While pilots can express preferences about their flight routing, including requesting a STAR or indicating 'No STAR,' ultimately, it is ATC that has the authority to determine if the use of a STAR is suitable for the specific flight scenario. This gives ATC the flexibility to optimize air traffic management, ensuring that STARs are used effectively based on real-time conditions rather than solely at the pilot's request.

Other options suggest restrictions or requirements on when ATC can issue a STAR that do not align with standard ATC procedures regarding STAR usage.
