What is the purpose of a Unicom station?

The purpose of a Unicom station is fundamentally to facilitate advisory communications, particularly for general aviation and private aircraft. Unicom stations operate on a designated frequency that allows pilots to share important information regarding their intentions and operations at non-towered airports. This includes announcing arrivals, departures, and intentions to taxi, take off, or land.

In addition to providing essential advisory services, Unicom stations aid in Civil Defense communication, ensuring that private aircraft can receive notifications or directives relevant during emergencies or special operations. This aspect is crucial for maintaining safety and awareness among pilots operating in uncontrolled environments where air traffic control may not be available.

The other options do not fully capture the primary function of a Unicom station. For example, while they may contribute to flight safety, they do not primarily control air traffic or specifically focus on flight training, so they do not align as closely with the definition and purpose of a Unicom station.
