Definition
The defined paths that aircraft follow between two points, typically established along airways, between navigation aids, or via published procedures. A route specifies the lateral track an aircraft will fly, including any waypoints, fixes, or navigation aids used along the way.
Plain English
The path you fly to get from one place to another. It is the line you draw on the chart connecting your departure point, any points along the way, and your destination.
Context Anchor
Seen in flight planning, navigation charts, and air traffic control clearances.
Derivation
From Old French 'route' meaning 'a way, path, or course,' itself from Latin 'rupta via' -- literally 'a broken or beaten way.' The original sense of a cleared path carries directly into aviation: a route is the established way through the sky.
Why Pilots Care
Following correct routes ensures separation from other traffic and compliance with airspace rules.
Intuition Check
Do not assume a route is just any path the pilot feels like taking. In aviation, a route is usually planned, published, or assigned, and the pilot is expected to follow it unless it is changed.
Example Sentence 1
ATC cleared the flight on a direct route to the destination, bypassing the published airway.
Example Sentence 2
Direct routing was approved by ATC instead of the standard airways route.
