What is the procedure for performing a VOR check?

The procedure for performing a VOR check involves tuning to the specific VOR frequency, ensuring that the receiving equipment indicates the correct radials, and documenting the results of this check. Tuning to the frequency allows the pilot to receive the VOR signal and verify its accuracy against known reference points. Proper indication is confirmed by observing if the course deviation indicator (CDI) and the TO/FROM indicators display the expected results when the aircraft is positioned on the selected radial. Documenting the results is essential for maintaining accurate flight data and for compliance with regulations, ensuring that any discrepancies can be addressed before flight operations proceed.

Other options do not address the specific requirements of a VOR check. Observing landmarks while flying at low altitude focuses on visual navigation rather than instrument checks. Communicating with ground control is relevant for operational safety and air traffic management but does not constitute the VOR check procedure itself. Relying solely on GPS coordinates does not involve using the VOR system, which is crucial for this specific navigation check.
