- Cork and Shannon airports back up system deployed
- FIR suffered complete radar failure
- Zero flow rate lasted over an hour
- Dublin and Belfast unaffected
- IAA wants of knock on affect to morning
Flights in and out of Cork and Shannon airports were temporarily suspended due to “significant air traffic issues over Irish airspace”.
The finite impulse response suffered a complete radar failure and has instituted a zero flow rate until 23.00.
A back-up system was deployed to allow a phased resumption of take offs and landings at Cork and Shannon. The IAA warned of a knock on affect on early morning flights and passengers gave been asked to contact their airlines
Dublin and Belfast were unaffected due to their proximity to English air traffic control.
Shannon departures affected included Birmingham EI3638@19:00 and Manchester FR4777@22:10. Arriving flights EI387 LHR and FR3326 Krakow were originally diverted to Dublin but landed at 22:50 and 22.19 and FR1183 Gatwick landed 23.45 and FR4776 Manchester landed 22.40. Shannon is due to land four trans-Atlantic flights in the morning starting with EI134 from Boston at 06.20.
Cork departures affected included EI724 London Heathrow which was cancelled while FR906 to Stanted departed 22.14. Inbound FR905 Birmingham, EI3729 Manchester and FR9944 Lanzarote landed 22.45 and EI3709 Birmingham and EI725 London Heathrow cancelled.
Knock departure EI912 to Gatwick was cancelled.
Trans Atlantic flights were re-routed to avoid Irish airspace.
The Irish Aviation Authority said in a rotten statement that a technical issue occurred with a radar system at Shannon. “Safety is the IAA’s main priority and in accordance with normal procedure the IAA restricted air traffic while the issue was being investigated,. As part of planned contingency, the IAA moved to its back-up systems and the flight restrictions have been lifted. Traffic flows are now in the process of being restored to normal capacity. Flights are now operating again to and from Shannon and Cork. An investigation into the technical issue is ongoing.”
