Editorial: Lessons must be learned after air traffic control issues

When taking a journey involving a flight, only the most optimistic traveller would fail to consider possible delays emerging at some point in their itinerary.

​There are many factors which can cause delays at airports, such as baggage handling problems or adverse weather conditions. And the late departure of a plane can have a domino effect to that airline's schedules for the rest of the day.

Now, it almost seems, the British traveller can add another occasional impediment to the list of delay-inducing hazards which has the potential to affect their journey times – air traffic control (ATC) issues.

Yesterday, an ATC issue saw flights delayed in Northern Ireland, Scotland and northern England.

It was the second ATC issue within two weeks to cause flight disruption.

Earlier this month, a software fault caused more than 2,000 flights to be cancelled, disrupting hundreds of thousands of passengers. A preliminary report, published last Friday, said the fault occurred in the software that allocates codes to individual aircraft and that it happened “in the space of a millisecond”.

National Air Traffic Services (Nats) chief executive Martin Rolfe confirmed the September 8 incident was a software issue, and not related to a Nats outage in 2023 or a radar issue in July last year. Unfortunately, Mr Rolfe has again found himself in the headlines all too soon, with calls for his resignation after yesterday’s disruption amid accusations that he has presided over “repeated system failures”.

On the world stage, it’s a poor look for the UK to be experiencing such air traffic control problems, not to mention the disruption to people’s lives. As investigations continue, it’s vital that lessons are learned and confidence restored in this critical piece of national infrastructure.
