Intersections on enroute charts are used as what?

• A. Airports used for refueling
• B. Named by pilot choice for private routes
• C. Weather reporting stations
• D. Named points defined by the crossing of radials and used as routing waypoints

Answer: (B)

Intersections are fixed navigation fixes defined by the crossing of radials from navigation aids, and they serve as routing waypoints on enroute charts. Because two or more radio aids’ radials intersect at a precise point, that spot becomes a named fix pilots and controllers use to define a flight path between airways. These points are published and standardized, so ATC can clear a flight from one fix to another and pilots can compute distances and courses between known locations. They’re not airports, weather stations, or pilot-chosen private route points; they’re predefined, published fixes used to structure IFR routing.
