Radiation threat exposes computer flaw
Airbus grounded thousands of planes after discovering that intense solar radiation can disrupt vital flight control computers. The move caused worldwide delays because around 6,000 A320 aircraft have the same vulnerability. Most planes will return to service once they receive a quick software update.
Regulators caution travellers about disruptions
The UK aviation regulator warned that passengers may face delays and cancellations, although airports report only limited impact so far. Airbus identified the flaw while investigating an October incident where a jet flying between the US and Mexico suddenly lost altitude. The JetBlue aircraft diverted to Florida after several passengers suffered injuries.
Several Airbus families share the defect
The issue affects the A318, A319, A320 and A321 models. About 5,100 planes only need a simple three-hour update. Another 900 older aircraft need full computer replacements and cannot carry passengers until engineers finish the job. The timing depends on the availability of replacement units. Airbus apologised for the resulting disruption.
Airlines take different approaches
An aviation analyst told a London news outlet that this event is highly unusual. Passenger disruption will vary depending on how fast each airline completes its updates. British airports report mild effects. Gatwick mentioned some disruption while Heathrow confirmed no cancellations. Manchester Airport expects no major problems.
Airlines feel the strain at different levels. British Airways appears less affected. Wizz Air and Air India already started updates. Public data shows Air France faces the greatest impact, with roughly 50 cancelled flights at its Paris hub. A travel journalist reported this using open flight schedules. EasyJet initially expected delays but later said it completed many updates and plans a full Saturday service.
Thanksgiving rush intensifies pressure in the US
In the United States the issue emerged during the busy Thanksgiving travel period. American Airlines said 340 planes need updates and warned of some delays but expects to finish most fixes by Saturday. Delta said the impact on its network should remain limited.
Australian carriers experience cancellations
In Australia Jetstar cancelled 90 flights after confirming that about a third of its fleet requires updates. The airline expects continued disruption through the weekend even though most planes already received the patch.
Safety officials emphasise strong standards
A senior UK aviation official said the Airbus notice will bring delays and cancellations over the coming days. He stressed that aviation remains extremely safe because of strict maintenance standards. He described the widespread grounding as a very rare event.
The UK transport secretary said British airlines appear only lightly affected. She praised the swift response and highlighted global safety standards for enabling such fast action.
Solar radiation corrupts key altitude calculations
The flaw involves software that calculates aircraft elevation. Airbus found that high-altitude solar radiation can corrupt this data. That caused the October altitude loss. Airbus said no other cases are known.
Europe’s aviation safety agency ordered all affected planes to receive updates before flying with passengers again. Aircraft may still operate ferry flights without passengers to reach maintenance bases. The A320 family uses fly-by-wire controls, meaning computers interpret pilot inputs instead of mechanical linkages.
