what happened to procedural control. don't they have a contingency/ back-up plan? |
I don't believe they have any controllers that can operate procedural control

If so, that is pathetic. Shannon do not warrant nav charges if that is the case. |
I think you'll find London and Scottish FIRs would be in the same boat. Procedural fallback has not been an option for at the very least 25+ years.
|
The only area unit in the UK or Ireland that has a procedural fallback is Oceanic.
I started at Prestwick Centre in 1991, there has never been a procedural fallback since way before that date. |
This makes me wonder whether Ireland needs to enforce ADS-B use, as Australia already does. Area-wide radar is looking a bit old-fashioned at this point. There should be no single point of failure in such a critical function.

@bnt, it all depends on what actually failed.
If the data feed to all the displays was lost ( remember that my PC friends ! ) with the radars or ADS receivers still working, you are still stuffed. |
Sounds like the system is still in a failure mode, and whilst flights are operating normally,the system itself is running in contingency mode.
Statement from the Irish Aviation Authority: 08:10 – October 3The IAA continues to investigate the technical issue which occurred in Shannon Airport last evening. Services to and from Shannon and Cork are operating normally on the IAA’s Shannon back-up system.The IAA’s Dublin system was unaffected and Dublin flights are operating normally. The Dublin system is independent of the Shannon system. https://www.iaa.ie/news/2018/10/03/s...8-10-october-3 |

I took the "radar" bit of the report literally i.e. as a failure of the radar itself, not any of the IT systems between the dish and the controllers! |

Were overflights affected? Most at cruise crossing Ireland. Shanwick has no radar coverage beyond 200 miles so oceanic is procedural. |
I saw an article which stated that there was a problem with cpdlc so transit traffic would have been affected. |

Apparently so - The info from our Ops people last night was as stated in the OP, it was the Shannon FIR was effectively closed for all business. We had a couple of planned west-bounds out of LHR last night that were either going to be replanned to avoid Shannon or held on the ground TFN...fortunately the situation improved fairly quickly. |
Time to send a few controllers to Khartoum for some refresher training in procedural separation. Two weeks should do? :O |

Good one but even Khartoum has radar now, since quite some time even :-)
