Plain English Meaning
Spots along an airway where you stop using the VOR station behind you and start using the next VOR station ahead. They tell you when to retune so your navigation signal stays strong and reliable.
Full Definition
Designated points on a Victor airway, marked on en route charts, where a pilot navigating between two VOR stations switches the navigation receiver from the station behind to the station ahead. Changeover points are normally placed at the midpoint between two VORs, but are published at a different location when terrain, signal range, or airway geometry require an earlier or later switch.
Context Anchor
Seen on and in planning when flying along based on VOR stations.
