Definition
Low-altitude airways in the United States that are defined by VOR (Very High Frequency Omnidirectional Range) ground stations and run from 1,200 feet above the surface up to but not including 18,000 feet MSL. They are designated as 'V' routes (called Victor airways) and form the backbone of the low-altitude IFR en route structure, providing predefined courses between navigation aids that pilots can fly using VOR receivers.
Plain English
VOR airways are the standard low-altitude highways in the sky for instrument flying. They are straight-line routes drawn between VOR ground stations, and pilots follow them by tuning in the stations and tracking the published course on their cockpit instruments.
Context Anchor
You see VOR airways on IFR en route low-altitude charts when planning or flying an instrument route.
Derivation
Named for the VOR stations that define them. 'Airway' simply means an established air route, just as a roadway is an established road. The 'V' on charts and the spoken name 'Victor' come from the phonetic alphabet letter for V.
Why Pilots Care
They provide predictable paths that keep aircraft separated and simplify navigation during instrument flight.
Analogy
A VOR airway is like a highway drawn in the sky. You cannot see the road, but the chart and navigation signals tell you where its centerline is.
Intuition Check
Do not read “airway” here as simply “airspace” or “any path an airplane can take.” A VOR airway is a specific published route tied to radio navigation signals.
Example Sentence 1
ATC cleared the flight from Bakersfield direct to the Avenal VOR, then via V107 to Paso Robles.
Example Sentence 2
Before takeoff the crew confirmed the VOR airways shown on the low altitude chart matched their clearance.
