I say this because I suspect it may be explained away as a sim fault.

So either A) the exercise didn’t involve MCAS and there was a simple sim fault ( no big deal for Boeing)
or
B) the exercise involved simulating an aircraft fault and MCAS came into play ( big deal for Boeing to have this exchange take place).
That’s how I read it.


Two guys have rampant MCAS operations - when it should not operate!

Not a big deal?

That alone should have rang massive alarm bells - they were not having an arvo out in a toy, they were testing and evaluating a aircraft (to be sure it was safe).

We know the simulators were faulty (now) as they do not correctly simulate the manual trim wheel forces required.

Testing seems to be the "Tick n Flick" option and if you do not get the result in the sim, the sim is to blame or get an exclusion.

Why was the "Shocker Alert" - MCAS now active down to M.2 said.

I read that as is it - is not a good thing, regardless of if there were a simulator fault or not.

The comments about the regulator indicate we are missing some important details in that text exchange -
