Which of the following is the maximum allowable degree difference during a dual VOR check?

The maximum allowable degree difference during a dual VOR check is 4 degrees. This standard is based on the requirements set forth by the Federal Aviation Administration (FAA) for ensuring the accuracy and reliability of VOR navigation systems. When performing a VOR check, pilots tune two VOR receivers to the same frequency and compare the readings. The 4-degree tolerance ensures that both systems are operating correctly and provides an acceptable margin for discrepancies that could arise from instrument inaccuracies or slight variations in signal reception. By adhering to this maximum difference, pilots can confidently navigate using VOR systems, knowing that their instruments are synchronized and operational within safe limits. If the readings exceed this tolerance, it indicates a potential malfunction in one of the systems, prompting further investigation or maintenance before flight.
