What is the function of a VOR receiver check?

The primary function of a VOR (VHF Omnidirectional Range) receiver check is to verify the accuracy of the VOR signals. This process is critical for ensuring that the aircraft's navigation system is providing the correct information to the pilot regarding their position and course relative to the VOR station. An accurate VOR signal is essential for navigation, as it allows pilots to determine their bearings and make informed decisions about their flight path. Regular checks help to confirm that the VOR receiver is functioning correctly, thereby enhancing flight safety and navigation reliability.
