What is the frequency for uncontrolled airspace with unassigned aerodromes?

The frequency designated for uncontrolled airspace, particularly for non-towered (unassigned) aerodromes, is 122.75 MHz. However, the closest standard frequency utilized for such operations, as reflected in the choices given, is 126.7 MHz. This frequency is commonly used for public and private traffic, allowing pilots to communicate when operating in uncontrolled airspace where there is no specific tower frequency assigned.

In uncontrolled airspace, pilots use this frequency to self-announce their positions and intentions, facilitating situational awareness and safety among multiple aircraft operating in the area. Utilizing a common frequency helps prevent misunderstandings and enhances the ability to navigate safely in less structured environments compared to controlled airspace.

In the context of drone operations, being familiar with these communications protocols and using the correct frequencies is crucial for both compliance and safety. Understanding the role of this frequency further aids drone pilots in knowing how to interact with other airspace users effectively.
