Takwis,
Thanks for the further explanations clarifying your previous answer, which I now accept.
At least until I understand the Boeing logic of using two vanes to lift a LE flap
A simple mechanical solution vs the electronic logic of MCAS ?!!
The use of a large (larger) engine cowl strake adds questions to the originating theme of the extent aerodynamic changes.
If the overall change requires additional inner-wing stall strips, then why use an aerodynamic cowl ‘fence’ to isolate the inner wing, normally achieved by the stall strip.
