Full Definition
Routes designed and printed on VFR aeronautical charts to help pilots transition through, around, or beneath complex airspace such as Class B and Class C areas. They include four types: VFR Flyways, VFR Corridors, VFR Transition Routes, and Terminal Area VFR Routes. Each is shown on a VFR Terminal Area Chart or sectional and includes recommended altitudes, headings, and waypoints to keep VFR traffic of conflicting flows.
