Yes I followed that discussion on discord. It's just that there needs to be a general random failure trigger of some sort with mean time, which I was trying to accomplish this way; I think something like PMDG or FSLABS did (1 random failure every ~10h, if you wish so) would be a popular feature here, it greatly increases immersion if you have a reason to do checklists and watch the engines & co. during cruise.
I understand the reason with training, but there is no sense in training if the situation can never occur outside of the training (well, unless you are a real 650 pilot). But I did not want to engage into that discussion here, so thank you for your feedback.
