What frequency range is designated for Aircraft Frequency Range?

The frequency range designated for Aircraft Communication is specifically between 118 MHz and 137 MHz, which falls under the Very High Frequency (VHF) range. This band is primarily utilized for air-to-ground and air-to-air communications, allowing pilots and air traffic control to exchange information critical to flight safety and operations.

This VHF range is advantageous for aircraft communications due to its ability to provide good signal propagation characteristics over long distances while maintaining a suitable quality of transmission important for voice communications. Additionally, the frequencies within this range are less affected by the physical obstructions found in urban environments compared to higher frequency bands.

The other frequency ranges mentioned do not pertain to routine aircraft communications. The range of 300 - 3,000 MHz is more aligned with other communication applications, including radar and satellite communication. The 30 - 300 kHz range is typically designated for Very Low Frequency (VLF) communications, often used for navigation and time signals. Lastly, the 3 - 30 GHz range includes Microwave and some satellite communications but is not utilized for standard air traffic communications.
