Which frequency should pilots use when operating at an uncontrolled aerodrome with no ground station?

When operating at an uncontrolled aerodrome with no ground station, pilots should use a specific frequency designated for communication among pilots. The selected frequency, 123.2 MHz, is commonly used for this purpose and is known as a general aviation frequency. It allows pilots to self-announce their intentions and position in the absence of air traffic control or other ground station operations, enhancing situational awareness and safety.

Using 123.2 as the communication frequency helps to establish a standardized practice across various uncontrolled aerodromes, facilitating better coordination among pilots in the airspace. This frequency is widely recognized within the aviation community for u controlled environments where there is no active ground station.

Other frequencies listed, such as 121.5 MHz, are designated as distress and emergency frequencies and should not be used for routine communications. Frequencies like 118.0 MHz are typically assigned to specific air traffic control services, while 122.8 MHz is another common frequency, but not as universally used as 123.2. Thus, 123.2 is the most appropriate choice for conducting operations at uncontrolled aerodromes.
