[SystemSafety] Technical information on Airbus A320 recall?

[David MENTRÉ]

Hello,

I've heard on the news that Airbus is recalling all its A320 planes due 
to issue of the "control software with solar radiations". Do you know 
where I can find more technical details of the issue and Airbus' 
workaround(s)? Sometimes the news tell about software updates, sometimes 
about hardware update.

As typical issue with solar radiations is to flip bits randomly in the 
computer, I'm curious about how a software update could solve the issue.

Best regards,
david
