Radio-frequency Spectrum
In the context of aviation, the Radio-frequency Spectrum refers to the part of the electromagnetic spectrum where electromagnetic waves are used for communication and navigation purposes. This spectrum ranges from 3 kHz to 300 GHz. In aviation, specific frequencies within this spectrum are allocated for various purposes such as air traffic control communication, aircraft navigation systems, weather radar, and collision avoidance systems. For instance, VHF (Very High Frequency) band, specifically between 108 and 137 MHz, is used for both communication and navigation in aviation. The use of the radio-frequency spectrum in aviation is regulated by international agreements and national laws to ensure interference-free communication and navigation. Misuse or unregulated use of the spectrum can lead to serious safety issues. Therefore, the allocation and management of the radio-frequency spectrum is a critical aspect of aviation safety and efficiency.
