What is the purpose of the Common Traffic Advisory Frequency (CTAF)?

The purpose of the Common Traffic Advisory Frequency (CTAF) is to coordinate traffic among pilots at uncontrolled airports. This frequency allows pilots to announce their intentions, such as takeoff, landing, or taxiing, to each other, enhancing situational awareness and safety in areas where air traffic control services are not available. By communicating on the CTAF, pilots can share valuable information about their own positions and actions, which helps in avoiding collisions and promoting a smoother flow of traffic. The use of CTAF is particularly important in uncontrolled airspace, where pilots must rely on their ability to see and avoid one another.

The other options do not align with the purpose of the CTAF; it is not solely for communication with air traffic control, as that typically occurs on different designated frequencies. While weather information can be shared over various means, it is not the primary function of the CTAF. Filing flight plans with the FAA is a separate procedure that involves different communications and does not utilize the CTAF.
