Glitch blamed for grounding of flights to and from two Irish airports.
A technical issue occurred with a radar system in Shannon, grounding flights in Irish airspace to and from Cork and Shannon airports. Dublin Airport was unaffected.
Last night (2 October) at around 10.45pm IST, the Irish Aviation Authority (IIA) confirmed that a technical issue occurred with the Shannon air traffic control (ATC) system.
‘The Dublin ATC is independent of the Shannon system. The technical issue is with the IAA’s Shannon-based system, which also services Cork – hence the earlier impact on Shannon and Cork’
– IRISH AVIATION AUTHORITY
It is understood the radar problem affected all flights coming from the west and south of Ireland, preventing flights from being processed by the ATC. It is understood that Dublin’s proximity to the UK’s ATC systems enabled flights to take off and land normally.
“Safety is the IAA’s main priority and, in accordance with normal procedure, the IAA restricted air traffic while the issue was being investigated. Flights to and from Shannon and Cork were affected by the restriction. Dublin was not affected,” the authority said.

“The technical issue is with the IAA’s Shannon-based system, which also services Cork – hence the earlier impact on Shannon and Cork. The investigation into the technical issue is ongoing and, as part of planned contingency, services continue to be operated on backup systems.”
Relying on the backup system, flight restrictions were eventually lifted, with traffic flows restored to normal capacity.
Both Shannon and Cork Airports confirmed that flights have resumed, albeit at a slower pace. Passengers travelling to and from Shannon and Cork airports are being urged to check the status of their flights with airlines.
Flights have resumed @CorkAirport following activation of a back up system by the IAA. The last scheduled departure to London Stansted with @Ryanair has taken off and further arrivals are due presently. Most flights are now expected to operate to schedule on Wednesday morning. pic.twitter.com/ff2Zh4L97P

Flights are now operating at Shannon Airport. The IAA moved to its back-up systems & flight restrictions have been lifted.
Traffic flow here is currently operating at a slower pace & we would advise passengers travelling tomorrow to check their flights. Thank you pic.twitter.com/JccqybeoVW
