A standard terminal arrival route, or shortly STAR, is a published route that can fly an airplane flying on an instrument flight rules (IFR) airplane by the air traffic controller just before it approaches an airport. The entire procedure (landing points, prescribed heights and usually also speeds) is then fixed. Description Star of Zurich Airport
A STAR covers the last part of the flight, usually from the "top of descent" and follows multiple waypoints until the start of the final approach to the landing run on which to land. A typical STAR consists of one or more starting points, the transitions, from which the procedure can be started, depending on which direction or from which airway one comes. From such a transition, the plane can fly to a point close to the airport via a scheduled route, from which one can fly an initial approach or the plane becomes "gevectored" (traffic directions heading) to the final approach .
Not all airports have published STARs, but most airports have one or more STARS.
To separate STARs, a name and sometimes a number and / or letter will be assigned. For example, at Schiphol you will find the Norku 2B arrival, coming from the east of the country.
A STAR can apply to one runway, but may also apply to multiple jobs.
Not all STARs are intended for IFR flights. Sometimes a STAR is also published for visual approaches. Clearly visible points on the ground are used instead of waypoints or radio stations.
STARs can be very detailed (as is often the case in Europe), so that air traffic controllers can fly the approach on their own behalf, for which air traffic control has given them permission. Sometimes they are free summier (like in the United States), but additional instructions are given by the air traffic control.
An IFR STAR closes on the ending to an airport, such as an instrument landing system, so that the path from the plane to the landing can be recorded.
