   "Toulouse, France, 28 November 2025 – Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.

   Airbus has consequently identified a significant number of A320 Family aircraft currently in-service which may be impacted.

   Airbus has worked proactively with the aviation authorities to request immediate precautionary action from operators via an Alert Operators Transmission (AOT) in order to implement the available software and/or hardware protection, and ensure the fleet is safe to fly. This AOT will be reflected in an Emergency Airworthiness Directive from the European Union Aviation Safety Agency (EASA).

   Airbus acknowledges these recommendations will lead to operational disruptions to passengers and customers. We apologise for the inconvenience caused and will work closely with operators, while keeping safety as our number one and overriding priority."

     @nyrath @SecureOwl There are layers of protection against the influence of (solar) radiation. Some are physical (shielding), some are hardware (e.g. ECC RAM), some are software, for instance, maximizing the Hamming distance between the possible values of a variable or implementing some additional self-correcting redundancy for critical data. This could be a reason that a single make and model would be affected, as not all models share the same software (or in this case software version).

     I am no aerospace engineer, but it seems to me highly unlikely that the vulnerability is restricted to this make and model of aircraft.
