Airbus Alerts on Solar Radiation Risk for 6,000 A320 Jets

Airbus, the European aircraft manufacturer, issued an urgent safety alert on Friday for approximately 6,000 A320 family jets worldwide, warning that intense solar radiation could corrupt critical flight control data and compromise aircraft stability. The directive follows an incident last month on a JetBlue flight from Cancun, Mexico, to Newark, New Jersey, where the plane experienced an sudden, uncontrolled drop in altitude, forcing an emergency landing in Tampa, Florida.

Investigators determined that solar radiation interfered with the plane's elevator-aileron computer, known as ELAC 2, causing a temporary loss of accurate positioning data. No injuries were reported, but the event highlighted a vulnerability in the A320's fly-by-wire system, which relies on electronic inputs to manage flight parameters such as pitch and roll. Solar flares or coronal mass ejections can release charged particles that penetrate Earth's atmosphere, potentially disrupting avionics at high altitudes by altering electron behavior in sensors and connectors.

The A320 family, including the A319, A320, and A321 models, is the world's most popular narrow-body aircraft, with over 12,000 delivered globally....
