Am I right in thinking that - even with the 'fix' - there will be no clear indication to the pilot that MCAS has kicked in? If the difference between AOA sensors is less than 5.5 degrees, does this mean that even the little mustard 'AOA-disagree' alert won't show, but MCAS will fire if other conditions are met?

I guess this means that pilots will have to infer that MCAS is live from the uncommanded AND, having quickly checked whether the other conditions apply (flaps, autopilot)?

I can't see that this does much to advance the pilot's ability to diagnose the problem. Why can't some space be found for a flashing red 'MCAS active' alert to show exactly what's happening?
