What is the first priority for air traffic controllers?

The primary responsibility of air traffic controllers is to ensure the safety and efficiency of air traffic. This involves separating aircraft to prevent collisions, issuing safety alerts when necessary, and providing support to national security initiatives. By prioritizing the separation of aircraft, controllers actively manage the airspace, ensuring that each aircraft maintains a safe distance from others during all phases of flight.

This priority is paramount because the safety of passengers and crews aboard all aircraft is the foundational rule of air traffic management. While the other functions of providing weather information, issuing clearances, and handling communications are important aspects of air traffic control, they support the overarching objective of maintaining safe separation between aircraft and ensuring overall safety in the airspace.
