It is weird, though, that this was not caught in simulations (not training simulations, but in design simulations.) I would assume that running simulations to see how the design behaves when sensors fail would be an absolutely standard thing to do. I don't work on airplanes, but we routinely simulate sensor failures and their effect on software systems and you'd think this would not be optional for passenger aircraft certification.
- salawat 8y agoWhen all of your testing is in house, and you don't have people who are willing to put the project at jeopardy for the sake of doing it right, you'll be amazed what can get overlooked. If anything, the process of engineering is most difficult in that answering most questions tends to be straightforward (not easy, but straightforward once you know the right methods to apply), while figuring out if you've asked all the right questions is the thing that keeps me awake at night. If you don't ask and dig in until you've answered it fully, it's easy to get blind sided. I have difficulty believing it could have gone so horribly wrong now, but I can't deny that just from the information available, even if MCAS isn't the root cause of the Ethiopian Air crash, there is some egregious failures in sound practice going on with Boeing to have slipped up this badly. That's the thing with sound Engineering, when you do it, it just verks. When you don't...
