Aircraft fly in 3 dimensions and when you are in the clouds or at night with no horizon it is impossible to get your mind to overcome spatial disorientation. When you lose an AOA and or other sensor and you AP kicks off you have to figure out which data being given to you is correct.
I don’t care how experienced you are it is a struggle. Add in top of that an 8 page Boeing checklist filled with what is no longer working or may be working plus additional procedures that must be accomplished and it gets ugly. The main goal is to not crash. And if you can successfully recover the aircraft it doesn’t matter how ugly everything in between was.
If the FAA demands perfection they will never get it. It is too complicated. The fact that these pilots survived in the sim is a major plus and good for them.
Apparently this is not how FAA is viewing things, at least according to Bloomberg's reporting of FAA's letter to Boeing.
I wonder if FAA would deem JT043 a failure because procedures weren't followed yet everyone on board survived without injury.
I wonder if pass/fail criteria other than survival can be developed, given how many different scenarios there are.
