What is the first duty priority of the air traffic controller?

• A. Communicating with pilots
• B. Separating aircraft and issuing safety alerts
• C. Coordinating with ground services
• D. Documenting flight plans

Answer: (B)

The first duty priority of the air traffic controller is to ensure the safe and orderly movement of aircraft within controlled airspace. Separating aircraft and issuing safety alerts encompasses the vital responsibility of preventing mid-air collisions and ensuring that aircraft maintain safe distances from each other. This function is paramount, as it directly relates to the safety of all individuals aboard the aircraft and on the ground.

While communicating with pilots, coordinating with ground services, and documenting flight plans are important tasks, they support the overarching goal of safety. However, the immediate priority remains the separation of aircraft to avoid accidents and ensure safe air traffic management. Therefore, the emphasis on this duty reflects the critical nature of maintaining safety as the core responsibility of air traffic controllers.
