Definition
FAA documents that capture the technical specifications of published en route airways, including the route's identifier, the navigation aids or fixes that define it, the courses between those points, segment distances, minimum en route altitudes, minimum obstruction clearance altitudes, and changeover points. These records are the source data the FAA uses when it designs, charts, and maintains the airway system.
Plain English
Official FAA records that list every detail of a published airway: where it starts, where it ends, the points and navigation aids that define it, the headings and distances between those points, and the lowest altitudes you can legally fly on each segment.
Context Anchor
Seen in IFR en route chart and route-record discussions, especially when an airway is being described from one fix or navigation point to the next.
Derivation
En route' comes from the French phrase meaning 'on the way' — the portion of flight between departure and arrival. 'Airway' is a defined corridor of airspace used for navigation. So an en route airway record is simply the official paperwork describing one of those in-between corridors.
Why Pilots Care
Ensures the navigation system follows the correct published airway routing and altitude restrictions, preventing route deviations.
Intuition Check
Do not read records here as a pilot’s logbook or flight history. In this context, records are the published route data that define an airway.
Example Sentence 1
The minimum en route altitudes shown on the low-altitude chart are taken directly from the en route airway records.
Example Sentence 2
Database updates must include the latest en route airway records to reflect any temporary flight restrictions.
