🔍 Key Concepts

• VHF (Very High Frequency) band definition in radio communications • Typical frequency range used for civil aircraft voice communications • Differences between navigation aids (like VOR/ILS) and voice comms frequencies

💭 Think About

• Which option matches the standard VHF band used for routine voice communication between aircraft and air traffic control? • Look at the ranges given: which one do you recognize as being used for navigation aids (like VOR or ILS) rather than voice? • Which option looks like it might belong to HF (High Frequency) rather than VHF?

✅ Before You Answer

• Confirm which numerical range is officially designated for aeronautical VHF voice communications in aviation references or your study materials. • Eliminate frequency ranges that are known for radio navigation aids instead of voice comms. • Eliminate any range that clearly fits within the HF (High Frequency) band (3–30 MHz) rather than the VHF band (30–300 MHz).
