In a massive technical operation carried out over a few hours, airlines completed software upgrades on thousands of Airbus A320s worldwide, after a problem was identified that could affect critical flight systems. Despite initial concerns, the impact on schedules remained minimal, with flight operations continuing as normal.
Only minor “disruptions” to airline flight schedules were caused by the rapid software upgrade on thousands of Airbus A320 aircraft worldwide, after a problem was identified that could affect critical flight systems.
In the United Kingdom, companies acted “immediately and in close coordination” with airports during Friday night, in order to complete the required updates on the “vast majority” of their aircraft, the country’s Civil Aviation Authority (CAA) announced.
According to the CAA, although there was initial concern over potential flight cancellations, very few flights were affected, and passengers experienced only minor issues. Only a small number of British carrier aircraft still await software or hardware upgrades, with no significant disruption expected for the public, the Authority emphasized.
The scope of the problem and Airbus’s response
Airbus announced on Monday that of the approximately 6,000 A320-family aircraft potentially affected, the “vast majority” have now received the necessary modifications. Fewer than 100 aircraft worldwide are still awaiting completion of the work to return to normal service.
The issue arose after analysis of a recent A320 incident showed that intense solar radiation could corrupt critical data affecting flight control systems. EASA issued guidance on Friday evening calling for “preventive action” by all A320 operators.
How the airlines responded
The largest British airlines operating A320s – easyJet, Jet2.com, Wizz Air, Titan Airways, and British Airways – proceeded immediately with the required updates.
At easyJet, more than 200 aircraft needed upgrades. The company completed all work over the weekend, with no impact on its flight schedule.
At Wizz Air, the mandatory software upgrade was completed on 83 aircraft on Friday night, without any cancellations.
British Airways completed the upgrade on just three affected aircraft, and flights continued normally.
Jet2.com confirmed that the necessary upgrades were completed without any impact on its operations.
“Example of coordination”
CAA chief Rob Bishton publicly thanked the companies and the European Union Aviation Safety Agency, EASA, for their swift mobilization and effective coordination:
“Thanks to the quick and diligent action of the carriers, British aviation was able to minimize passenger inconvenience,” he said.
With upgrades now completed worldwide and most aircraft already returned to full operation, airlines are continuing their schedules normally, maintaining operational stability ahead of the winter season.
