Where can you find VOR checkpoints?

• A. A/FD
• B. VFR Sectional Chart
• C. IFR Supplement
• D. Airport Facility Directory

Answer: (A)

VOR checkpoints are official ground-reference points used to verify your VOR receiver’s accuracy as part of the required VOR check. The authoritative place to find these published checkpoints is the Airport/Facility Directory. The A/FD gathers navigation aids and related testing information for airports, including the locations of VOR check points and how to use them for a valid VOR check.

These checkpoints aren’t shown on VFR Sectional Charts, which focus on visual navigation features, airspace boundaries, and basic airport data. The IFR Supplement covers procedures and IFR navigation data, but it does not serve as the go-to catalog for published VOR check locations. Since you need reliable, up-to-date information on where to perform a VOR check, the A/FD is the appropriate source.
