The Z symbol with numbers on top and bottom on a chart depicts which of the following?

• A. NAVAID Changeover Point With Mileage To NAVAIDS
• B. VOR Service Volume Boundary
• C. Airway Termination Point
• D. Grand Circle Route

Answer: (A)

This symbol marks a changeover point along an airway where you switch navigation from one VOR to another. The numbers shown above and below are the distances in nautical miles to the two NAVAIDs that bound that segment, so you know exactly when you should switch sources to keep accurate guidance. It’s a handy way to plan your nav as you move from one beacon to the next. This symbol is distinct from others that depict VOR service volume boundaries, airway terminations, or Grand Circle Routes, which are shown with different chart conventions.
