To illustrate how STARs can be used to simplify a complex  clearance and reduce frequency congestion, consider  the following arrival clearance issued to a pilot flying to  Seattle, Washington, depicted in Figure 3-11: “Cessna 32G,  cleared to the Seattle/Tacoma International Airport as filed.  Maintain 12,000. At the Ephrata VOR, intercept the 221°  radial to CHINS Intersection. Intercept the 284° radial of the  Yakima VOR to RADDY Intersection. Cross RADDY at 10,000.  NAVAID, intersection, or fix where all the various (en route)  transitions to the arrival come together. A STAR en route  transition is a published segment used to connect one or  more en route airways, jet routes, or RNAV routes to the  basic STAR procedure. It is one of several routes that bring  traffic from different directions into one STAR. This way,  arrivals from several directions can be accommodated on  the same chart, and traffic flow is routed appropriately  within the congested airspace.  3-13  Figure 3-11. STAR interpretation.
