Which frequency range is used for Air Traffic Control Services?

The frequency range used for Air Traffic Control Services spans 119.9750 to 121.9625 MHz. This segment is specifically designated for VHF air traffic control communications, which are essential for ensuring clear and effective communication between air traffic controllers and pilots.

The VHF band is intentionally allocated for aviation purposes because it provides reliable voice communication over considerable distances while minimizing interference, which is crucial in the busy environment of air traffic management. The frequencies within this range are used for various functions, including ground control, tower communications, and en-route air traffic control.

Understanding this frequency allocation is vital for pilots and aviation personnel to ensure compliance with communication protocols and to maintain safety in the airspace. The other options refer to different ranges that may not be allocated for primary air traffic control use, thereby reinforcing the importance of recognizing the correct frequency for efficient aviation operations.
