Definition
A Standard Terminal Arrival (STAR) is a pre-published instrument flight procedure that connects the en route phase of a flight to an approach at the destination airport. It provides a standardized routing — typically a series of fixes, altitudes, and sometimes speed restrictions — that transitions arriving aircraft from the en route environment into the terminal area in an orderly, predictable way. STARs are issued by ATC as part of the IFR clearance and are depicted on dedicated arrival charts.
Plain English
A STAR is a published, named arrival route that takes you from cruise into the area around your destination airport. Instead of ATC reading you a long string of fixes and altitudes one at a time, they assign you a STAR by name and you fly the route as printed on the chart.
Context Anchor
You will see STARs on instrument procedure charts, in flight planning, and in air traffic control clearances when arriving at larger or busier airports.
Derivation
Standard means a published, repeatable procedure everyone uses. Terminal refers to the airspace and ATC environment around an airport (as opposed to en route, which is the cruise portion between airports). Arrival is self-explanatory. So a STAR is a standard, published way to arrive into the terminal area.
Why Pilots Care
Following a STAR reduces radio calls, keeps traffic flowing smoothly, and helps manage descent and speed.
Intuition Check
Do not read “terminal” as the airport building. In this term, “terminal” means the controlled airport area where arriving and departing traffic is being organized.
Example Sentence 1
Cleared to Denver via the FLATIRONS THREE arrival, descend via the STAR.
Example Sentence 2
The crew briefed the STAR before descent to ensure the proper crossing altitudes were set.
