How often must a VOR be inspected?

• A. Every 30 days
• B. Every 6 months
• C. Every 12 months
• D. Every 5 years

Answer: (A)

Ensuring VOR accuracy requires a check every 30 days. This regular VOR check verifies that the navigation signal you’re relying on is within acceptable limits, so the bearing read from your instruments reflects the actual bearing to the station. A VOR check can be performed using a VOT facility, an approved airborne check, or other FAA-approved methods, and the result is logged in the aircraft’s maintenance records. The 30-day interval keeps the navigation system dependable for IFR operations. The other time frames refer to different maintenance cycles and are not the cadence for VOR checks.
