Global Fleets Halted Amid Safety Concerns
Airbus grounds thousands of aircraft after discovering that intense solar radiation can disrupt essential flight control computers, causing worldwide delays. Approximately 6,000 A320-family jets are affected, representing half of the company’s global fleet. Most planes can return to service after a quick three-hour software update. The UK aviation regulator warns of potential delays and cancellations, though airports report limited impact.
October Incident Triggers Investigation
Airbus uncovers the problem after examining an October incident 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 Fixes and Hardware Replacements Underway
About 5,100 aircraft require only a software update. Another 900 older planes need full computer replacements and cannot carry passengers until replacements are complete. The timeline depends on the availability of replacement units. Airbus apologises for the operational disruption affecting passengers and airlines.
Airports Report Mixed Impact
An aviation analyst calls the situation highly unusual and notes that passenger disruption depends on each airline’s update speed. Gatwick reports some delays, while Heathrow experiences no cancellations. Manchester Airport expects minimal problems. British Airways faces limited issues, while Wizz Air and Air India have already begun updates.
Airlines Work Quickly to Limit Delays
Data shows Air France faces the greatest disruption, with around 50 cancelled flights from its Paris hub on Saturday morning, according to travel experts. EasyJet expects some delays but says many aircraft already received updates and plans a full Saturday schedule. In the US, the issue coincides with the busy Thanksgiving travel period. American Airlines reports 340 affected planes and warns of potential delays but expects most updates to complete by Saturday. Delta anticipates limited disruption.
Australian Flights Also Cancelled
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 jets already underwent 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.
Authorities Highlight Strong Safety Response
The UK transport secretary says the impact on British airlines is limited. She welcomes the swift global reaction and emphasises strong international aviation safety standards.
Radiation Corrupts Critical Elevation Software
The issue involves software that calculates aircraft altitude. Airbus finds that intense solar radiation at high altitudes can corrupt this data. The October incident was the only known occurrence of its kind. The European aviation regulator issues an emergency directive requiring all affected aircraft to receive updates before passenger flights resume. Aircraft may operate ferry flights without passengers to reach maintenance facilities.
Fly-By-Wire Systems Require Precise Data
The A320 family uses fly-by-wire controls, where pilot inputs pass through computers rather than mechanical links. Accurate software is essential for safe flight operations.
