And my statement isn’t specifically to anything especially aeronautical. Anytime you change hardware, software, firmware, and use new things and make new configurations, and change the way control systems monitor and interpret, change vendors for parts, change what computer chips you’re using, hell, even what wiring you’re using to connect everything, new and different problems can arise that were not present in prior planes (or subs, or cars, or boats) because they are different parts and materials and vendors and configurations.
I mean problems can arise in machines that were working just fine but they change a vendor for a part and that part isn’t as good as the prior part, and now they’re getting failures they never had before. It is totally possible given the complexity of these systems.
The THEORY behind how the systems of things is the same, but the physical systems themselves, being designed and made differently can cause problems in one that are not present in another.
