Thousands of Planes Affected Across the Globe
Airbus grounds thousands of aircraft after discovering that intense solar radiation can disrupt flight control computers, causing global delays. Around 6,000 A320-family planes are affected, representing half of Airbus’ worldwide fleet. Most jets can return to service after a three-hour software update. The UK aviation regulator warns of flight delays and cancellations, though airports report limited disruption.
Investigation Follows October Altitude Incident
Airbus identifies 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 flaw also affects the A318, A319, and A321 models.
Software Updates and Hardware Replacements Underway
Approximately 5,100 jets need only a software update. Another 900 older planes require full computer replacements and cannot carry passengers until the work finishes. The schedule depends on replacement availability. Airbus apologises for operational disruption affecting passengers and airlines.
Airports Report Mixed Levels of Disruption
An aviation analyst describes the situation as highly unusual and says passenger impact depends on each airline’s approach to updates. Gatwick reports some delays, while Heathrow has no cancellations. Manchester Airport expects minimal problems. British Airways faces limited disruption, while Wizz Air and Air India already progress with updates.
Airlines Work Quickly to Minimise Delays
Data indicates Air France faces the largest impact, with around 50 cancelled flights from its Paris hub on Saturday morning, according to travel experts. EasyJet expects some disruption but says 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 warns of delays but expects most updates to finish by Saturday. Delta anticipates limited disruption.
Australian Airlines Also Cancel Flights
Jetstar cancels 90 flights after confirming that about a third of its fleet is affected. Disruption is expected to continue through the weekend even though most planes already received updates. A senior UK Civil Aviation Authority official warns of possible delays and cancellations but emphasises 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 is limited. She welcomes the rapid international response and highlights strong aviation safety standards.
Radiation Interference Corrupts Altitude Software
The problem lies in software that calculates aircraft elevation. Airbus discovers that 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 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 crucial for safe flight operations.
