What is the frequency range of an aircraft's Very High Frequency (VHF) communications?

• A. 120.000 MHz to 140.975 MHz
• B. 118.000 MHz to 136.975 MHz
• C. 117.000 MHz to 135.975 MHz
• D. 119.000 MHz to 137.975 MHz

Answer: (B)

The frequency range of an aircraft's Very High Frequency (VHF) communications is correctly identified as 118.000 MHz to 136.975 MHz. This range is specifically allocated for civil aviation communications, which include air traffic control communications and other related operational uses. This frequency range is critical for reliable voice communication between pilots and air traffic controllers, ensuring safety during flights. The range is also chosen for its ability to provide stable radio coverage, favorable propagation characteristics, and sufficient bandwidth for clear communication. The other frequency options do not align with the established VHF communication band for aircraft operations. The specified range of 118.000 MHz to 136.975 MHz is well-defined in aviation regulations and is recognized internationally, making it essential for pilots and air traffic controllers to adhere to; hence, it is the standard frequency band for VHF communication in aviation.
