It's easy to say with the hind sight. When you are flying a plane, which starts to behave abnormally, you have to analyze hundreds of possible causes and try not to kill everyone on board at the same time. There are multiple reports about poor MCAS manuals and lack of training.

In the case of runaway stab trim, this is not correct. Runaway stab trim is trained for, should be obvious, and the corrective action is in the manual and pilots are trained to handle it.

If runaway stab trim caused by MCAS is indeed what's happened it might not have been obvious enough.

It could well be that it is obvious for anyone with the proper training, but then maybe not all airline pilots get the proper training? Or if they have the training but are pushed to hard in the name of cutting costs, and profits?

However, if it indeed was expected to be obvious to all pilots, why even - as I understand it - have the warning on the optional HUD?

Seems like bad safety engineering to have extraneous warnings possibly increasing cognitive load in a a crisis situation.

Yeah, it’s so obvious that pretty much every country in the world agreed to ground that killing machine...

Effectively they are also grounding untrained pilots.
