The unspecified problem was with the Enhanced Tactical Flow Management
System, which helps to manage air traffic by comparing demand and capacity
of different air traffic control sectors.
It manages up to 36,000 flights a day. Some 29,500 were scheduled on Tuesday when the fault occurred.
When the system failed, Eurocontrol's contingency plan for a failure in the
system deliberately reduced the capacity of the entire European network by
10%. It also added what it calls "predetermined departure intervals" at
major airports.
