How should a pilot make a VOR receiver check when on the designated checkpoint on the airport surface?

To conduct a VOR receiver check on the airport surface, the correct procedure involves setting the Omni Bearing Selector (OBS) to the designated radial for the VOR checkpoint. When the VOR receiver is properly functioning, the Course Deviation Indicator (CDI) will center within plus or minus 4 degrees of that radial, and it must show a FROM indication.

This procedure is important because it confirms that the VOR receiver is accurately tuned to the correct frequency and is capable of providing navigational information reliable for flight operations. When the CDI is centered as specified, it demonstrates that the VOR equipment is functioning properly and the pilot can trust the information it provides during flight.

The other options do not provide the correct approach for a VOR check. For instance, simply setting the OBS to a random heading or inquiring about the signal reception quality does not achieve the goal of validating the accuracy of the VOR system against the predetermined radial.
