There is no information in the current B738M AOM that tells crews that the "MCAS cycles between the left AoA and the right AoA sensor". What is the source for the above statement?
my quote tells you LANCS THINKS it is in the Lion Air thread, which is why I started my post off with IF IT IS TRUE..
As the crew cannot do anything about it ie cannot select which one, why bother giving them that info, Ground crew need to know IF it switches because if there is a fault reported not being able to tell which one was in use means they HAVE to check both, personally I don't believe this to be correct info.. However if it is true my suggestion would IMHO improve the system.
