Irish Aviation Authority

[2] Until 30 April 2023, the IAA was also responsible for providing air traffic control services to Ireland's three main airports, namely Dublin, Shannon and Cork, and en-route air traffic control services over Irish airspace.

In recent years, the authority has invested more than €115 million in air traffic control systems.

Minister for Defence Simon Coveney said the increased surveillance capability would give better coverage of the Atlantic airspace over which the IAA has responsibility for civil and military aircraft.

[4] The safety and regulatory division and the air navigation services of the IAA were split into two separate organisations on 30 April 2023.

The air navigation service provider functions of the IAA were transferred to a new ANSP called AirNav Ireland.
