Re: Boeing 737MAX Grounded Worldwide Q3 2019

Perhaps a reference to http://www.b737.org.uk/mcas.htm#fix is helpful? It says: MCAS will be limited to operate only for one cycle per high AoA event To me, this describes a discrete/binary event rather than a continuous/varying event. Does anyone have a better description? I am more interested if ...

Would it be better for QF to replace the 787 on the PER-LHR route with the A35K ULR once it will be selected and "downgrade" the 787 for shorter routes but with more payload? The A35K ULR will most probably bring more payload for the PER-LHR route.
