Definition
A route for which an IFR altitude has been established and published on aeronautical charts. Published routes include Federal Airways, Jet Routes, Area Navigation (RNAV) Routes, and Specified Direct Routes.
Plain English
An officially charted IFR route with an assigned altitude, drawn on aeronautical charts so pilots and controllers can use it as a known, named pathway through the airway system.
Context Anchor
You may see this term in IFR flight planning, route clearances, and FAA route descriptions.
Derivation
Published comes from a Latin idea meaning “to make public.” In aviation, that helps because a Published Route is not just a path someone wrote down; it is a route officially made available for pilots to use.
Why Pilots Care
Using published routes ensures compliance with airspace rules and simplifies coordination with air traffic control.
Intuition Check
Do not assume Published Route means any route that appears in print or on a screen. Here it means an official FAA route with instrument-flight altitude information established for it.
Example Sentence 1
ATC cleared the flight via a published route to the destination, assigning V23 at 8,000 feet.
Example Sentence 2
ATC assigned a published route to keep the flight clear of temporary flight restrictions.
