Airbus Orders Emergency Software Rollback After Solar Radiation Risk Detected

Airbus has ordered urgent software fixes across 6,000 A320-family jets after discovering that intense solar radiation can corrupt data used by flight controls. The issue surfaced after an October 30 JetBlue flight from Cancun to Newark suddenly lost altitude and diverted to Tampa. The FAA has issued an emergency airworthiness directive requiring aircraft to revert to earlier software before flying, with some jets also needing hardware replacements.

A solar radiation risk forcing a software rollback is serious and rare.
