Step-by-step explanation:
The subject of this question is Aviation. CTAF stands for Common Traffic Advisory Frequency. It is an aviation term used to refer to a specific radio frequency used by pilots to communicate with other pilots in the vicinity of an airport or uncontrolled airspace.
The CTAF is used to announce and coordinate flight operations, such as takeoffs, landings, and any other activities that may affect the safety of aircraft in the area. It helps pilots to maintain situational awareness and avoid collisions while operating in the same airspace.
For example, if a pilot wants to land at an airport, they would listen to the CTAF for that airport to gather information about any other aircraft in the area and announce their intentions before landing.
