FAA Part 107 Drone Practice Test

Which is not a function of the Common Traffic Advisory Frequency (CTAF)?

1. Self-announcement by pilots

2. Coordination of drone flights

3. Directing traffic by ATC

4. Facilitating communications at non-towered airports

The correct answer is: Directing traffic by ATC

The correct answer highlights that directing traffic by Air Traffic Control (ATC) is not a function of the Common Traffic Advisory Frequency (CTAF). The primary role of the CTAF is to enhance situational awareness among pilots, particularly in uncontrolled or non-towered airport environments. When pilots self-announce their positions and intentions, they contribute to a shared understanding of the traffic environment, which is crucial for maintaining safety. This self-announcement feature is especially useful as it allows pilots, including those operating drones, to coordinate and communicate their movements without ATC intervention. Additionally, the CTAF serves as a channel for facilitating communications at non-towered airports, promoting awareness and coordination among multiple pilots in the vicinity, but it does so without any direct control over traffic. Drone operators, while they must adhere to regulations, also benefit from the CTAF by providing their positions and intentions, aiding in the safe integration of various aerial activities. However, ATC does not use the CTAF for directing traffic in a controlled manner; that function is reserved for communication in environments where air traffic is actively managed.
