What inspection is required for VOR equipment if used for navigation?

For VOR (VHF Omnidirectional Range) equipment used in navigation, the requirement is that the equipment must be inspected and operationally checked every 30 days. This requirement is specified in the Federal Aviation Administration (FAA) regulations to ensure that the VOR system is functioning properly and providing accurate navigational information.

The 30-day inspection ensures that pilots have reliable navigation aids at their disposal, which is particularly crucial for VOR, as it is a primary means for maintaining navigational accuracy during flight operations. This operational check involves testing the VOR equipment to verify that it displays the correct information and is working within prescribed tolerances.

While there are other inspections for aviation equipment, such as annual or 24-month checks for specific systems, they do not apply to VOR equipment when used for navigation. The 30-day timeframe specifically targets the VOR system's need for regular verification in order to maintain safety and operational integrity during flights.
