What frequency range includes VHF communication for aircraft?

• A. 118 - 137 MHz
• B. 30 - 300 MHz
• C. 300 - 3,000 MHz
• D. 3 - 30 GHz

Answer: (A)

The frequency range of 118 - 137 MHz is designated for VHF (Very High Frequency) communication specifically for aircraft operations. This band is part of the VHF aeronautical mobile service and is used for air traffic control communications and other aircraft communications. The frequencies in this range are critical for pilots and ground controllers to maintain contact during various phases of flight, ensuring safe and effective air traffic management. Other frequency ranges provided do not pertain to VHF aircraft communication. The range of 30 - 300 MHz encompasses various VHF usages, but it is too broad and includes frequencies not exclusively assigned for aviation. The ranges of 300 - 3,000 MHz and 3 - 30 GHz fall into the UHF (Ultra High Frequency) and microwave bands, respectively, which are not utilized for traditional VHF air traffic communications. Thus, the specific range of 118 - 137 MHz is essential for maintaining robust communication in aviation operations.
