Radiation threatens flight computers
Airbus grounded thousands of aircraft after discovering that intense solar radiation can disrupt vital flight control computers. The move caused worldwide delays because about 6,000 A320 planes share the same vulnerability. Most aircraft will return to service after a quick software update.
Regulators warn travellers of disruptions
The UK aviation regulator cautioned passengers about possible delays and cancellations, though airports report only limited impact. Airbus uncovered the flaw while investigating an October incident in which a jet flying between the US and Mexico suddenly lost altitude. The JetBlue aircraft diverted to Florida after several passengers were injured.
Several Airbus families affected
The problem spans the A318, A319, A320 and A321 models. Around 5,100 aircraft need only a simple three-hour software patch. Another 900 older planes require full computer replacements and cannot carry passengers until engineers complete the job. The schedule depends on the supply of new hardware. Airbus apologised for the disruptions.
Airlines face different levels of strain
An aviation analyst told a London news outlet that the situation is highly unusual. Passenger disruption will vary depending on how quickly each airline completes updates. British airports report limited problems. Gatwick noted some disruption while Heathrow reported no cancellations. Manchester Airport expects no significant issues.
Airlines experience uneven impact. British Airways appears lightly affected. Wizz Air and Air India already began updates. Public data suggests Air France suffers the greatest strain with roughly 50 cancelled flights at its Paris hub. A travel journalist highlighted this using open flight information. EasyJet initially warned of delays but later said it completed many updates and plans full Saturday operations.
US holiday rush complicates repairs
In the United States the issue appeared 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 predicted only limited impact.
Australian carriers cancel trips
In Australia Jetstar cancelled 90 flights after confirming that around one third of its fleet needs updates. The airline expects continued disruption through the weekend even though most planes already received the patch.
Safety bodies stress strong standards
A senior UK aviation official said the Airbus warning will lead to delays and cancellations in the coming days. He stressed that aviation remains extremely safe because of strict maintenance systems. He described the mass grounding as a very rare event.
The UK transport secretary said British airlines appear only lightly affected. She praised the fast response and pointed to strong global safety rules.
Solar bursts corrupt altitude software
The flaw involves software that calculates aircraft elevation. Airbus learned that strong solar radiation at high altitudes can corrupt this data. That caused the October altitude loss. Airbus said no similar cases are known.
Europe’s aviation safety agency ordered affected aircraft to receive updates before carrying passengers again. Planes may still operate ferry flights without passengers to reach maintenance bases. The A320 family uses fly-by-wire controls, meaning computers process pilot inputs instead of mechanical linkages.
