Simulator capacity needn’t be an issue
Not sure where you are located, but sim time has been at a premium for quite a few years. Used to be, if we wanted to check something out quick, we could just run down to the sim, not anymore. Booked up with all the newbies especially.
The crux of this is how to identify and deal with STAB TRIM RUNAWAY
MCAS isnt stab trim runaway. If it was that simple, there would simply be an off switch. MCAS was a cure for the problems, but doesnt solve the problems.
You have high AoA stall, low speed stall, and high G maneuver stall problems to deal with. That is not a dashboard light and software patch fix.
I thought the software fix was in and that the aircraft had done a few hundred test flights and found to be fine - safe and ready for return.
According to Boeing, the software fix has not been submitted to the FAA for review. It also appears that the 'testing' has been, for the most part, in the sim, not actual flights.
Currently, the Congressional Committee is handing the Lazy B theirs B's.
