alt Hacker NewsI would argue that designing avionics without EDAC is negligent design by Airbus.
Most modern servers at least implement ECC on their RAM. I would expect flight electronics to be designed to a higher standard.

Until relatively recently, ECC on server RAM was because of chip failures and to lesser extent electro magnetic interference.
Good part selection and different EMI environment meant the calculated risks from not having ECC were considered too low to care and the idea that they might have to deal with radiation outside of flying near nuclear explosion arrived after the specific devices got designed.
Multi-module consensus is a form of EDAC - it's exceptionally unlikely that multiple units will fail identically simultaneously.
