Re: The reason that the Max series need MCAS

Essentially it depends on the plane but for some, perhaps most these days, the short answer is no. Keep in mind I haven't flown for some years due to old eyes and few dollars but some planes are fly-by-wire only meaning there is no mechanical or hydraulic backup. Typically there are "sufficient" redundant computers in the event of a failure, IIRC that's 3 so in the event of one being different it essentially gets out voted and ignored and assuming that two failures on a flight should be exceedingly rare.
