What is a common source of airport traffic information?

A self-announcement via the Common Traffic Advisory Frequency (CTAF) is a widely used method for providing airport traffic information. CTAF allows pilots in the vicinity of an airport to announce their intentions and positions, thereby enabling other pilots to be aware of traffic in the area, especially at non-towered airports. This helps maintain safety by providing situational awareness and promoting communication among pilots, ensuring they can make informed decisions while navigating the airspace near the airport.

While radar systems and direct communication with pilots contribute to traffic awareness, they are not as universally accessible or as common for every pilot as the CTAF method. Online flight tracking services can provide flight status data, but they typically do not offer real-time communication between pilots in the same way that the CTAF does. The CTAF is fundamental in a flight operation environment where real-time, local knowledge is essential for safety and efficiency in air traffic management.
