Nats said the issue had been with its planning system, meaning that flight plans had to be processed manually It apologised for the disruption caused by the fault and said it was "working closely with airlines and airports" to get things running as normal again

In the last few moments, UK air traffic control service Nats declared that it had "identified and remedied the technical issue" Here's a look at the latest developments on this story: So, the issue's been fixed - but the question now is how bad the knock-on delays will be for those caught up in today's disruption. It's all a big logistical puzzle and it will take several hours for all the pieces to be put back into place. The airlines will need to get them away so the delayed flights waiting to get back to the UK can take off and make their way home. And if that crew's hours expired while waiting on the ground, then the airline will need to find replacements to take over their flight.Īlso, there are now a whole load of airliners parked up at airports around the country taking up gate space. There are several reasons for that - not least getting delayed flights refuelled and their fare-paying customers on board - but also that some of the crews will have run out of hours in the meantime.įatigue is a big concern in aviation, so the hours pilots and cabin crew work are strictly regulated.

Nats' announcement at 15:15 BST that the problem with its air traffic planning system had been resolved means that airliners and their passengers should begin moving again - but there will still be disruption until the end of the day.
