What is a UNICOM facility?

A UNICOM facility is a communications service found at nontowered airports that provides a means for pilots to communicate with each other and with ground services. Typically, UNICOM frequencies are utilized by pilots to report their positions, intentions, and any relevant information as they approach or depart from the airport. This service plays a crucial role in enhancing situational awareness and safety at airports that do not have an operating control tower.

By allowing pilots on the same frequency to share information regarding their flight operations and intentions, UNICOM helps prevent conflicts and enhances coordination among aircraft and ground support at nontowered airports. This is especially important where a control tower is not present to manage air traffic, making effective communication essential for safe operations.

The other choices do not accurately describe a UNICOM facility: it is not associated with a local control tower, does not involve satellite communication systems, and is not limited to flight training schools.
