Global Flights Face Major Disruption
Airbus grounds thousands of planes after discovering intense solar radiation can interfere with flight control computers, causing worldwide delays. About 6,000 A320-family jets are affected, representing half of Airbus’ global fleet. Most aircraft can resume service after a three-hour software update. The UK aviation regulator warns of flight delays and cancellations, though airports report limited disruption so far.
October Altitude Incident Sparks Investigation
Airbus identifies the issue after investigating an October event where 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 flaw also affects the A318, A319, and A321 models.
Software Fixes and Hardware Replacements Underway
About 5,100 jets require only a software update. Another 900 older planes need full computer replacements and cannot carry passengers until work is complete. Timelines depend on replacement availability. Airbus apologises for operational disruption affecting passengers and airlines.
Airports Report Mixed Impact
An aviation analyst calls the situation highly unusual and notes disruption depends on each airline’s approach. Gatwick reports minor delays, Heathrow has no cancellations, and Manchester Airport expects minimal disruption. British Airways faces limited issues, while Wizz Air and Air India have already begun updates.
Airlines Act Quickly to Minimise Delays
Data shows Air France experiences the greatest disruption, with about 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 problem coincides with the busy Thanksgiving travel period. American Airlines reports 340 affected planes and expects some delays but aims to complete most updates by Saturday. Delta predicts limited disruption.
Australian Flights Also Cancelled
Jetstar cancels 90 flights after confirming roughly a third of its fleet is affected. Disruption is expected to continue through the weekend despite most planes 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 Global Action
The UK transport secretary says the impact on British airlines appears limited. She welcomes the rapid international response and highlights strong aviation safety standards.
Radiation Corrupts Critical Altitude Software
The problem involves software that calculates aircraft elevation. Airbus finds strong 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 aircraft to receive updates before carrying passengers. Aircraft may operate ferry flights without passengers to reach maintenance facilities.
Fly-By-Wire Systems Depend on Reliable Software
The A320 family uses fly-by-wire controls, where pilot commands pass through computers rather than mechanical links. Accurate software is essential for safe flight operations.
