What frequency range do VOR navigation aids operate in?

What frequency range do VOR navigation aids operate in?

• A. 108.00 to 117.95 MHz
• B. 960 to 1215 MHz
• C. 108 to 118 MHz
• D. 2.4 to 2.5 GHz

Answer: (A)

VOR navigation aids operate in the VHF band from 108.00 to 117.95 MHz. This specific range is reserved for aviation VOR signals, providing reliable omnidirectional bearings to aircraft. The upper limit, 117.95 MHz, keeps VOR clear of other systems that use nearby bands (for example, TACAN/UHF), and the lower limit at 108.00 MHz is the start of the VHF aviation navigation band. Options that lie in UHF or other bands (such as 960–1215 MHz or 2.4–2.5 GHz) aren’t VOR frequencies, and an upper limit of 118 MHz falls just outside the official range.
