What is surpirsing for me is that these are still occurring on the A380.
I agree that a new plane type would cause more problems on EIS but the A380 was flying for two more years than EIS.
The A380 delay was production related, wiring issues, not system design issues that the 787 suffered. This meant that the A380 was flying test missions for longer than most civil types and they should have ironed most of these bugs out.
I was not aware that the A380 flys with a lower cabin altitude, I thought only the 787 and A350 did.
