So Rolly, it looks like it (MCAS) acts through the stab trim. They quote ‘two switches’ to override, I imagine these would be the stab trim cutout switches?

Wondering whether it would be input to the system similar to the Speed Trim?

Sorry Hugh,

I no longer operate the 737 so cannot determine the intricacies of MCAS however it seems logical that it would be an extension of speed trim

If correct, how bloody frightening would that be. [emoji45]

I heard an ex Engineer from Boeing discuss that the MCAS system was deliberately designed to remove control from the pilots and it could not be over ridden.
I’ll wait for the final report, however, if this is the case it is truly frightening.
Seems to go against Boeings philosophy, time will tell.
