The IAA provides air traffic management services including:
- Air Traffic Control
- Flight information
- Alerting and search and rescue services
- Aeronautical information
- North Atlantic Communications
The IAA employs over 300 air traffic controllers Dublin, Cork and Shannon and 50 radio officers at Ballygirreen, Co. Clare, who ensure the safe, orderly and expeditious flow of air traffic. This is achieved using various tools, such as radar, radio and on-board aircraft systems. The standard separation between aircraft is 1,000 feet in the vertical plane or five nautical miles in the lateral plane, although there are some exceptions.
In 2017, over 1.1 million flights were safely managed by Irish air traffic controllers and radio officers in Irish airspace. This was the busiest year on record for the IAA, with an increase of 2.5% on traffic levels in 2016.
