VOR navigation radios used for IFR operations must be checked for accuracy every how many days?

• A. 15
• B. 30
• C. 60
• D. 90

Answer: (B)

In IFR (Instrument Flight Rules) operations, VOR (VHF Omnidirectional Range) navigation radios are critical for ensuring accurate navigation during flight. The regulations stipulate that these navigation radios must be checked for accuracy every 30 days to ensure that pilots can rely on them for safe navigation. This 30-day requirement is set to maintain the integrity of the instrument during flight operations, as even small deviations over time can affect a pilot's ability to navigate accurately. Regular checks help to verify that the VOR equipment is functioning correctly and that the readings it provides are reliable, thus avoiding potential navigation errors during flight. While other intervals such as 15, 60, or 90 days may seem reasonable, they do not align with the established FAA requirements for IFR operations. Adherence to the 30-day check is crucial for flight safety and operational compliance.
