Massive Disruption Across Global Fleets
Airbus grounds thousands of aircraft after discovering intense solar radiation can interfere with flight control computers, triggering worldwide delays. Around 6,000 A320-family jets are affected, representing half of the manufacturer’s global fleet. Most planes can return to service after a three-hour software update. The UK aviation regulator warns of flight delays and cancellations, though airports report only limited disruption.
October Incident Prompts Investigation
Airbus uncovers the problem after examining an October event in which a plane flying between the US and Mexico suddenly lost altitude. The JetBlue aircraft makes an emergency landing in Florida after at least 15 passengers are injured. The vulnerability also affects the A318, A319, and A321 models.
Software Updates and Hardware Replacements Underway
Approximately 5,100 aircraft require only a software update. Another 900 older jets need full computer replacements and cannot carry passengers until the work is complete. The schedule depends on replacement system availability. Airbus apologises for the operational disruption affecting passengers and airlines.
Airports Report Mixed Impact
An aviation analyst calls the situation highly unusual and says disruption depends on each airline’s upgrade approach. Gatwick reports minor delays, while Heathrow sees no cancellations. Manchester Airport expects minimal problems. British Airways faces limited impact, and Wizz Air and Air India already began updates.
Airlines Work Rapidly to Limit Delays
Data shows Air France experiences the most disruption, with around 50 cancelled flights from its Paris hub on Saturday morning, according to travel experts. EasyJet expects some delays but confirms many jets already received updates and plans a full Saturday schedule. In the US, the issue emerges during the busy Thanksgiving travel period. American Airlines reports 340 affected aircraft and expects some delays but aims to finish most updates by Saturday. Delta predicts limited disruption.
Australian Flights Also Cancelled
Jetstar cancels 90 flights after confirming about one third of its fleet is affected. Disruption is expected to continue through the weekend, despite most jets already receiving updates. A senior UK Civil Aviation Authority official warns of possible delays and cancellations but stresses aviation remains extremely safe. He calls the grounding a very rare event.
Officials Praise Swift Response
The UK transport secretary says the impact on British airlines is limited. She welcomes the rapid international reaction and highlights strong global aviation safety standards.
Solar Radiation Corrupts Elevation Software
The flaw affects software that calculates aircraft altitude. Airbus finds solar radiation at high altitudes can corrupt this data. The October incident was the only known occurrence. The European aviation regulator issues an emergency directive requiring all affected planes to receive updates before carrying passengers. Aircraft may operate ferry flights without passengers to reach maintenance facilities.
Fly-By-Wire Systems Rely on Accurate Data
The A320 family uses fly-by-wire controls, where pilot inputs pass through computers rather than mechanical links. Reliable software is essential for safe flight operations.
