FAA Ground School Practice Test

What is one of the specific roles of UNICOM frequencies?

1. To only provide weather updates

2. To manage air traffic signals

3. To facilitate communication at uncontrolled airports

4. To track aircraft movements

The correct answer is: To facilitate communication at uncontrolled airports

UNICOM frequencies serve a crucial function in the realm of aviation, especially at uncontrolled airports where there is no air traffic control tower. These frequencies allow pilots to communicate with each other and ground services, effectively coordinating their movements and operations. This interaction is vital for safely managing arrivals, departures, and other ground activities when air traffic controllers are not present to provide guidance. Using UNICOM frequencies, pilots can announce their intentions, such as takeoffs, landings, and taxiing, which enhances situational awareness among all users at the airport. This self-communication helps prevent conflicts and ensures that all aircraft and ground personnel are informed about ongoing activities. Thus, the role of facilitating communication at uncontrolled airports is essential to maintaining safety and efficiency in those environments.
