Definition
An identifier for a specific Military Training Route (MTR) flown under Visual Flight Rules (VFR), where the 'VR' prefix indicates a VFR route and '207' is the unique route number assigned by the FAA and the Department of Defense. A three-digit route number (such as 207) indicates that one or more segments of the route are flown above 1,500 feet AGL, while a four-digit number would indicate the entire route is flown at or below 1,500 feet AGL.
Plain English
VR207 is the name of a particular military training route that pilots fly using visual flight rules. The 'VR' tells you it's a visual route, and the number '207' tells you which specific route it is — and because the number has three digits, at least part of the route is flown higher than 1,500 feet above the ground.
Context Anchor
Seen on aeronautical charts and in route information when a civilian pilot’s planned flight path crosses or passes near a Military Training Route.
Derivation
VR' comes from 'Visual Route' — meaning it's flown under Visual Flight Rules. The number is simply the route's catalog identifier. The digit count (three vs. four) is a coding convention used to convey altitude information at a glance.
Why Pilots Care
Civilian pilots must know active VR routes to avoid conflicts with fast low-flying military traffic that may not be talking to air traffic control.
Intuition Check
VR207 is a route name, not a radio frequency, altitude, or waypoint. The number identifies the route; it does not tell you where the aircraft are at any given moment.
Example Sentence 1
During preflight planning, the pilot noticed her route would cross VR207 and checked the Chart Supplement to see when it was scheduled to be active.
Example Sentence 2
VR207 was listed as active on the day’s NOTAMs, so the flight stayed above the route’s altitude block.
