What is the frequency range classified as “very high frequency” (VHF) in aviation communication?

The classification of frequencies in aviation communication is crucial for understanding how different communication systems operate and interact. Very High Frequency (VHF) is specifically defined within the electromagnetic spectrum for aviation and other communication purposes. The VHF range is recognized as spanning from 30 MHz to 300 MHz.

This frequency range is particularly significant because it supports line-of-sight communication between aircraft and ground stations, which is essential for reliable voice communication and navigation. VHF is widely used in air traffic control, aircraft communication, and radio navigation systems, contributing to safe and efficient flight operations.

Understanding that VHF encompasses frequencies from 30 MHz to 300 MHz allows pilots and aviation personnel to effectively use radios and other communication devices within this range, enabling clear communication and better situational awareness in the cockpit.

The other frequency ranges mentioned do not fall under the VHF classification, as they pertain to different categories of radio frequencies used for various applications, such as Ultra High Frequency (UHF) or Super High Frequency (SHF). This distinction is key for anyone involved in aviation to ensure they are using the appropriate communication frequencies for their operations.
