How should a pilot conduct a VOR receiver check at a designated checkpoint on the airport surface?

The correct method for conducting a VOR receiver check at a designated checkpoint on the airport surface involves setting the Omni Bearing Selector (OBS) on the designated radial and ensuring that the Course Deviation Indicator (CDI) centers with a FROM indication. This procedure is crucial for determining the accuracy of the VOR system. By achieving a centered CDI with a FROM indication, the pilot confirms that the VOR is functioning properly and providing reliable navigation information.

When the CDI is centered, it indicates that the aircraft is precisely on the chosen radial, which signifies that the VOR signal is properly aligned and the receiver is adequately calibrated. This check is vital for operational safety as it assures pilots that they can trust the navigation data they receive from the VOR throughout their flight.

Other options may suggest different radial configurations or indications that do not align with the standard procedure for a surface receiver check. This can lead to inaccurate navigational data, which is why the specified correct method is critical for ensuring effective flight operation.
