First big issue is that, the now 34 MAX simulators will actually need to simulate correctly. It seems that they have been substandard for some time, I expect that the simulators have received far less FAA oversight and scrutiny than the MAX ever did.

Should the MAX simulator be required to accurately simulate the full envelope with and without MCAS and accurately replicate the trim wheel forces, and should the simulator be compared to the aircraft independently of Boeing and the FAA to verify it simulates true aircraft performance?
Simulators when qualified are checked to ensure they accurately match the OEMs supplied data. Whether this simulates the true aircraft performance is somewhat immaterial as the regulators are only comparing OEM data to simulator data. Often this OEM data is gathered from engineering derived means as opposed to flight test data mainly (I suspect) as a cost saving exercise!

The TDMs and the operators very restricted (by regulators)to deviate from supplied data.
