Definition
Standard Terminal Arrival Routes designed using area navigation, allowing aircraft to fly from the en route environment to the destination airport along a published path defined by geographic waypoints rather than ground-based navigation aids. RNAV STARs are flown using onboard navigation systems (typically GPS or FMS) capable of meeting the required navigation performance specified for the procedure, and they often include published altitude and speed restrictions to streamline arrival sequencing.
Plain English
An arrival route into a busy airport that is flown using the aircraft's own navigation system, following a chain of named points rather than tracking signals from ground stations.
Context Anchor
You see RNAV STARs on arrival charts, in flight planning, and in air traffic control clearances during the descent toward a destination airport.
Derivation
RNAV stands for Area Navigation, meaning the aircraft can navigate directly between any two points within a defined area rather than only along straight lines between ground-based stations. STAR stands for Standard Terminal Arrival Route. Combined, RNAV STAR means a pre-designed arrival path flown by the aircraft's own navigation computer.
Why Pilots Care
RNAV STARs let pilots fly more direct, fuel-efficient paths, reduce radio congestion, and help manage speed and altitude constraints in busy terminal airspace.
Intuition Check
STAR does not mean a visual marker in the sky here. An RNAV STAR is not a shortcut the pilot invents; it is a published arrival route used when assigned or expected and when the aircraft is properly equipped for it.
Example Sentence 1
Cleared to descend via the EAGUL6 arrival, the crew loaded the RNAV STAR into the FMS and verified each waypoint and altitude restriction.
Example Sentence 2
The RNAV STAR included published speed restrictions that kept us at 250 knots until crossing the first fix.
