Airbus said a recent incident had revealed that solar flares may corrupt data critical to the functioning of flight controls.

This is incredibly interesting, I hope the final report includes specific details of the data corruption and what they did to fix it. Actually it’s more interesting because the fix is reverting to a previous software version so they somehow introduced a vulnerability to single event upsets I’m guessing. I’d love to know how often these sort of events happen (not just when they cause issues but bit-flips in general). I know that flying high they are exposed to higher levels of radiation than on the ground.
