An air traffic controller's first priority is separation of aircraft and ___.

• A. Issuance of safety alerts
• B. Updating of flight plans
• C. Issuance of traffic advisories
• D. Maintenance of NAVAIDs

Answer: (A)

Keeping aircraft separated is the top priority in ATC. When a potential loss of separation is detected, the controller must immediately issue safety alerts to the pilots involved. These alerts warn pilots of an imminent risk and prompt rapid corrective action to prevent a collision or unsafe proximity. Other tasks like updating flight plans, issuing traffic advisories, or maintaining NAVAIDs are important but do not address the urgent danger in the moment the separation is at risk. Traffic advisories inform pilots of nearby traffic, but safety alerts provide the urgent warning needed to avert an incident.
