Someone mentioned that the MCAS provides 10 secs of trim input when activated. Can that be correct/verified? 10 secs of trim input is massive on the 737. The stabiliser is a powerful secondary flight control and has known limitations - for example Boeing are explicit about overuse of stabiliser trim
during the approach to stall recovery. Positioning the stabiliser in such a sense can severely reduce elevator authority - was this not the contributing factor in the FlyDubai 738 crash in Rostov? Two separate variants, one without MCAS, but with the same concerns relating to pitch authority?
