Air traffic refers to the movement of aircraft in the sky and on the ground at airports. It includes commercial flights, private planes, and cargo aircraft. Air traffic control (ATC) is responsible for ensuring the safe and efficient flow of this traffic, guiding pilots during takeoff, landing, and while in flight. Air traffic is managed through a network of radar systems, communication tools, and procedures. Air traffic controllers use these systems to monitor aircraft positions and provide instructions to pilots. This coordination helps prevent collisions and ensures that flights operate on schedule, contributing to the overall safety of air travel.
