Those numbers are very hard to believe. Where are you getting them from?
The numbers are from the press, noting Boeing and American Airlines....

The airline stated it takes 80 hours to park each ac...so 100 to 150 to bring it out is not unreasonable...again, this is information direct from the airline.

Transit to park, button up the engines, etc...unbutton, required maint, transit....

who knows, it is what American stated in the press..

It's totally ass-backwards to put feel on the stick by moving a primary control surface. I thought the stick controlled the surface, not the other way round! To my mind if they need constant or increasing pressure on the stick as the aircraft enters a stall then B need to add a servo to the stick, not flap a primary control surface just because they can quickly hack into it's motors etc. It's sticky-tape Engineering..
Concur! an attempt to fix a problematic conventional flight control system with a half assed band-aid FBW solution. Blending the two on a critical system, innovative! How is that working out?

Ooooppps. AoA gone and MCAS cranks in a gob of nose down trim.
Exactly, so now, you shut down MCAS and the electric trim system. You must now manually trim the ac enroute to destination?
BTW, in this sim case, the AOA sensor is out, so you are to manually trim the ac enroute, without an AoA measurement??
So what will the FCOM say, land at the nearest airport?
