If pilots are trained in how to recognize the emergency and what to do, and they are instructed that in an actual emergency the forces on the trim wheel (presumably what they are referring to) will vary, they will respond appropriately. Simulators can't exactly replicate extreme conditions, upsets and whatnot.
If you're training for trim runaway it would be helpful to simulate the full forces but I'm not sure if it reflects a worrying lack of preparedness.
The most important fix is that the MCAS should not be able to put the trim in an extreme position, the fact that it did is quite worrying.
This particular article seems much ado about very little.

- RockyMcNuts 7y agoThat seems like a different issue. Root problem seems to be: Software puts trim in an extreme position. It should never do that. Aviation Week article: if you are in an electric trim runaway, you need to turn off electric trim, then in order to turn the trim wheel manually, you need to nose down to reduce aerodynamic forces. Seems necessary to train for which it suggests was not the case. NYT article: Simulator doesn't simulate the forces on the trim wheel correctly (although Aviation Week suggests they were able to simulate something useful) The NYT article really seems like the least of the problems.
