What is the frequency for a VOR inspection?

The frequency for a VOR (VHF Omnidirectional Range) inspection is indeed every 30 days. This regular inspection is essential to ensure that the VOR system is operating properly and provides accurate navigation information to pilots. The 30-day requirement is set by the Federal Aviation Administration (FAA) to promote safety in aviation by frequently verifying the VOR's performance and ensuring it meets regulatory standards. This ensures that pilots can rely on this navigational aid, which is crucial for instrument flight rules (IFR) operations. Regular checks help identify any discrepancies or malfunctions early before they can pose a risk to flight safety. It is important for pilots and maintenance personnel to adhere to this schedule to maintain operational readiness and compliance with FAA regulations.
