When can ATC issue a Standard Terminal Arrival Route (STAR)?

A Standard Terminal Arrival Route (STAR) is issued by Air Traffic Control (ATC) to provide a standardized path for aircraft arriving at an airport. This helps streamline arrivals and integrates them safely into the terminal airspace. The use of a STAR allows for more efficient management of air traffic and can enhance safety by providing structured routing to specific waypoints.

ATC will issue a STAR when it is deemed appropriate based on various factors such as air traffic conditions, weather, and airport capacity. It is essential that the route aligns with overall traffic management strategies and helps maintain safe separation between aircraft in busy terminal environments. Issuing a STAR can also aid pilots in maintaining compliance with air traffic procedures and enhance the predictability of arrival times.

In contrast, the other options do not reflect how STARs are typically issued. For instance, a STAR is not a response to a pilot's request being denied; it is provided proactively by ATC for systematic handling of arrivals. Additionally, STARs are not automatically given for all arrivals, as they depend on the specific situation and traffic flow. The notion that STARs are only issued during peak times also does not represent the operational practices of ATC, as they can be employed at any time that requires a structured approach to
