An error with European air traffic co-ordination could affect up to half of Tuesday’s 29,500 flights

Up to half of all European flights on Tuesday could suffer from delays due to a failure in one of the systems used to manage air traffic.Eurocontrol, which co-ordinates flights across the continent, said almost 15,000 scheduled trips “could have some delay”.Contingency plans put in place have reduced the network capacity by another 10%, it said.The problem is expected to be solved late on Tuesday evening.Eurocontrol said there had been a failure in its Enhanced Tactical Flow Management System. The system helps to manage air traffic by comparing demand and capacity of different air traffic control sectors.Air traffic control itself has not been directly affected, and Eurocontrol said there “are no safety implications arising from this incident”.”We have never had anything like this before,” a Eurocontrol spokesman told the AFP news agency. On Twitter, the group said that it regrets the inconvenience, but that “safety is our number one priority at all times”.

As from 1520 UTC, we have reopened the access to its flow management system while remaining in Procedural Contingency mode. This is the next step in re-establishing normal Network Manager operations, which is expected later tonight.— EUROCONTROL (@eurocontrol) April 3, 2018

Eurocontrol’s contingency plan for a failure in the system, published on its website, calls for reducing capacity of the entire European network by 10%, and adding what it calls “predetermined departure intervals” at major airports.”In this case, AOs (aircraft operators) concerned may expect high delays,” the plan says.Several European airports warned passengers to expect delays, with Brussels Airport saying it was limited to just 10 departures every hour. Schiphol in Amsterdam, Helsinki, and Dublin airports also warned passengers about delays of varied lengths.

Due to the @Eurocontrol system failure departures are now limited to 10/hour at #brusselsairport. We’re now assessing the impact for the next few hours and we’ll keep you up-to-date. https://t.co/ENMaLwktqg— Brussels Airport (@BrusselsAirport) April 3, 2018

On Tuesday, the group said the plan will be maintained for several hours, “until we are certain that sufficient data is in the system to allow it to operate completely correctly”.Eurocontrol also asked airlines to resend any flight plans filed before 10:26 UTC, which it says were lost in the system failure.Separately, employees of Air France are on strike for the fourth consecutive day, reducing the airline’s capacity by 25%.
