Amendment status on an instrument approach procedure refers to which of the following?

• A. The runway lighting configuration for the approach.
• B. The circulation date and revision number of the procedure.
• C. The aircraft's maintenance history.
• D. The current weather minimums for the approach.

Answer: (B)

Amendment status tells you whether the instrument approach procedure you’re using is current and exactly which version you have. It’s identified by the circulation date and the revision number. The circulation date shows when the chart was distributed or updated, and the revision number flags the specific version of the procedure. Together, they let you verify you’re flying the latest published routing, altitudes, procedures, and minimums, since changes can occur between publications.

The other items don’t reflect amendment status: runway lighting configuration describes the approach lighting setup, maintenance history isn’t related to the chart version, and weather minimums, while important, are not what amendment status indicates. Always check the chart’s amendment status to ensure you’re using the current procedure.
