Definition
A Standard Terminal Arrival Route (STAR) is a published IFR arrival procedure that connects an en route fix to a fix from which an instrument approach can begin. It provides a pre-planned transition from the en route phase of flight into the terminal area of a destination airport, with defined waypoints, courses, altitudes, and often speed restrictions.
Plain English
A STAR is a pre-set arrival path published on a chart. Instead of the controller giving you turn-by-turn directions all the way in, you fly the route as printed, which brings you from cruise down toward the airport and lines you up to start an approach.
Context Anchor
Pilots encounter STARs when planning an instrument flight, receiving an arrival clearance from air traffic control, or loading an arrival route into the flight management system.
Derivation
"Terminal" here refers to the terminal area — the airspace around an airport where arrivals and departures are handled. So a Standard Terminal Arrival Route is simply a standard, published route into that terminal area.
Why Pilots Care
Following the published STAR reduces radio calls, workload, and the chance of separation errors during high-traffic arrivals.
Intuition Check
Do not read “terminal” as the airport passenger building. In “Standard Terminal Arrival Routes,” it means the airspace around the destination airport where arriving aircraft are organized for approach and landing.
Example Sentence 1
Center cleared us to descend via the KPTON ONE arrival, so we loaded the STAR in the FMS and started down at the published crossing altitudes.
Example Sentence 2
We loaded the STAR into the FMS so the arrival waypoints would sequence automatically after the last en route fix.
