But Lemain, there's been no suggestion of any control issue with #1 until after landing. In fact I believe it's been officially stated that there was no problem with it until that point.
Though I feel bad being so blunt, as frankly, if I recall correctly, you're someone whose posts do tend to be on-topic!
Sure, I don't want to be a PITA and I agree that the engine control system appears not to have been an issue in this incident but it has exposed a 'problem'. Whether it's best to discuss that here or in another thread in another section It would be best if a number of engineers could provide input so they would need to know that the discussion was taking place -- informed discussion is so much more useful than conjecture.
I think the problem potentially goes much deeper than just engine controls. It was my greatest concern when electronics superseded mechanical and hydraulic systems in the first place. I do have a degree in electronics specialising in control and instrumentation with many years of military design experience in the field of things that go up and then bang when they've come down - some with rather big bangs. So the remarks I have made are considered. But I am not an aeronautical engineer.
Still, another thread would be good if anyone is interested and we could rope-in some engineers if anyone would like to start one? I mostly lurk so don't really want to start it off.
