Salute!
you are wrong, sky9
There are two vanes.
The problem is the MCAS switches from one to the other upon reset. Had Lion crew MCAS been using the good vane all they would have had would have been unreliable something or other warnings and no flight control interference. And no stick shaker for left seat guy.
I am more scared by what Aloha hints. AoA inputs and who knows what other things for the spoiler What other things on the MAX that we do not know, nor the pilots?
Gums sends.....
