#2Caused uncommanded pitch down, could exceed structural integrity of aircraft. There are redundant units - unknown why this can happen given redundancy.

Apparently it has happened to an Airbus once before.

#7Caused uncommanded pitch down, could exceed structural integrity of aircraft. There are redundant units - unknown why this can happen given redundancy.
Also not very clear how they attributed the failure to solar radiation.

#8So the patch will be physical, I imagine.

#9The title sounds like speculative clickbait.
From https://www.airbus.com/en/newsroom/press-releases/2025-11-ai...:
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.

Presumably the same affected units are part of the redundancy package. The article essentially says as much.
