Re: Why not just disable the system and put the planes back in the air?
We know by now that the planes CAN fly without the sensor and its attempted automatic corrections -- and probably fly safer without it -- so why not disable it and get them back in the air?
I have read that there is a minimum requirement for self-stabilising flight that probably cannot be met without MCAS.
There's also the consideration that MCAS was supposed to make flying the 737 MAX just like flying its predecessors, so no training required. Disable MCAS and all the airlines incur a training requirement, which they were assured they wouldn't need. Who pays for that?
