What does the acronym ATC stand for in aviation terminology?

The acronym ATC in aviation terminology stands for Air Traffic Control. This refers to a service provided by ground-based controllers who coordinate the movement of aircraft on the ground and through controlled airspace. Their primary role is to ensure the safe and efficient movement of air traffic by providing instructions, advisories, and information to pilots. They help manage the flow of air traffic at airports and en route, prevent collisions, and facilitate the orderly transfer of aircraft between different phases of flight, ultimately enhancing overall safety in the aviation sector.

Understanding the role of Air Traffic Control is crucial for anyone involved in aviation, as it plays a vital part in maintaining safety and efficiency in air travel. The other options refer to different entities that do not represent the central function of ATC within the aviation industry.
