Question

Question: 'VOR is an acronym for:'

Option 1: 'Very High Frequency Omni-Directional Range' — This is the standard expansion of VOR in aviation navigation. It denotes a ground-based radio navigation aid that operates in the VHF band and provides a magnetic bearing to pilots via a steerable signal, making it the correct choice.

Option 2: 'Nondirectional Radio Beacon' — This would spell NDB, which is a different type of navigational aid using non-directional signals, typically in the LF/MHF bands. It is not what VOR stands for, so this option is inaccurate for the acronym VOR.

Option 3: 'Very Old Radio' — This phrase does not correspond to any recognized aviation navigation aid, nor is it an expansion used for VOR. It is incorrect and misleading about the meaning of the acronym.

Option 4: 'Variable Omnidirectional Receiver' — While the term suggests a directional/receiving capability, it does not match the official name of the VOR system. The actual system name relates to a directional, yet fixed-reference broadcasting method, so this is not the correct expansion of VOR.

Connecting these ideas, the only option that aligns with the established aviation navigation term VOR is the first one, since VOR is specifically described as a Very High Frequency Omni-Directional Range, a foundational nav aid used by aircraft for precise bearings.
