The NAVAID changeover point is depicted by which symbol?

• A. Z symbol
• B. X symbol
• C. O symbol
• D. Triangle symbol

Answer: (A)

When guidance comes from a VOR or other NAVAID, you need to switch to the next facility before the current signal fades. The changeover point marks exactly where you should begin that handover to keep navigation continuous. On the charts used in this material, that point is shown with the Z symbol along the airway between the two NAVAIDs. The symbol is designed to stand out so you can plan your transition early and avoid losing signal. Other shapes on charts serve different purposes, so they don’t indicate where to switch NAVAIDs.
