Which frequencies are the airband frequencies?

Airband frequencies refer to the specific radio frequencies used for aeronautical communications between aircraft and air traffic control (ATC). The International Telecommunication Union (ITU) has allocated a range of frequencies for airband communications, which are standardized and used globally.

The airband frequency spectrum is divided into various bands, each serving different purposes:

1. VHF (Very High Frequency) Airband:

- VHF airband frequencies are used for primary voice communications between aircraft and ATC.

- Frequency range: 118.000 MHz to 136.975 MHz.

2. UHF (Ultra High Frequency) Airband:

- UHF airband frequencies are primarily used for secondary air-to-ground communications and data transfer.

- Frequency range: 225.000 MHz to 400.025 MHz.

3. AM (Amplitude Modulation) Airband:

- AM airband frequencies were commonly used in older aircraft and have been phased out in many regions.

- Frequency range: 255.000 MHz to 325.000 MHz.

It's important to note that specific frequencies within the airband spectrum may vary slightly from country to country due to local regulations and frequency allocations. Pilots and air traffic controllers are required to adhere to the designated frequencies and protocols established by their respective aviation authorities.
