What is the purpose of a STAR and how does it aid sequencing?

• A. A STAR is a published departure route used to vector aircraft away from the airport.
• B. A STAR is a published arrival route that sequences traffic toward the approach with predictable spacing.
• C. A STAR is a weather advisory product.
• D. A STAR is an instrument approach procedure.

Answer: (B)

A STAR provides a published arrival route that guides aircraft from en-route airspace into the terminal area and toward the initial approach with predictable spacing. This setup lets arrivals merge smoothly onto common tracks, reducing the need for constant vectors and helping controllers maintain the correct separation as aircraft approach the airport. By defining the path, altitudes, and sometimes speeds, STARs create orderly sequencing so each aircraft arrives at the approach in a predictable order and distance, enabling a clean handoff to approach control. They are not weather advisories, instrument approach procedures, or departure procedures.
