Airbus grounds A320 aircraft amid solar radiation risk

Curious how a software update can be rolled back to mitigate a "solar radiation risk" (which would typically imply a hardware radiation susceptibility issue). Perhaps the software update comes in the form of new EEPROMs, something like that?

Good point. Digging through the links (eight or nine deep) you eventually come to the actual directive:

It looks like the fix it to replace the elevator aileron computer (ELAC), which sounds like a hardware fix, not a software update rollback. But that sort of detail often doesn't survive repeated rounds of journalism.

I think that depends on the given aircraft’s configuration. Some it’s just a software change (revert to older version I think).

There are two of those units in each aircraft.

Still therefore confused how software knows about photons originating in the sun.

Probably more about how it handles data corruption and makes it not drop the nose for a few seconds when it sees it.

It'll be kind of like OTA Autopilot updates that can recognise corner cases like a big white semi trailer?
