Today it was reported that the MAX sims do not replicate MCAS recovery procedure properly and a software fix was required.

Has anyone been in a MAX sim? Did they use the stab trim switch config from the NG or the MAX?

Quote:

Stab Trim Runaway that has been in the 737 (and virtually every other aircraft with electric trim) emergency checklist and training regime since day one.

Sorry, but the STS runaway for the NG is not the same for the MAX due to the differences in the functionality of the stab trim switches...

also note that in sim testing, even at 250 kts, the manual trim wheel would not budge and they had to roller drive the ac to move the stab...IF that is the case with the MAX, that is a problem and outside of STS procedures, no?
