What frequency is used for Aerodrome Traffic Frequency where no ground station exists?

• A. 123.2 MHz
• B. 122.8 MHz
• C. 118.9 MHz
• D. 126.5 MHz

Answer: (A)

When there is no ground station at an aerodrome, pilots rely on a locally published Aerodrome Traffic Frequency to coordinate with other traffic in the area. This frequency provides a common channel for pilots to announce their positions, altitudes, and intentions, helping to prevent conflicts and maintain situational awareness in the vicinity of the aerodrome. The best choice, 123.2 MHz, is designated for this purpose. It’s the dedicated channel published for use when no ground-based communications facility is available, so everyone in the area uses the same frequency to share traffic advisory information. Before transmitting, listen first to check for ongoing traffic, then make concise, standard-position-and-intention broadcasts (for example, position, altitude, and planned runway or circuit direction). This keeps the airspace around the aerodrome orderly and safe. The other frequencies are used for different services or contexts and are not the published Aerodrome Traffic Frequency for zones without a ground station, so they wouldn’t provide the appropriate coordination channel in this scenario.
