What I fail to understand is why Boeing didn’t install two angle of attack sensors on EVERY airplane and why a warning light saying “MCAS ON” wasn’t installed. It also sounded to me as if there was a problem WITH the sensor … has that ever been determined? In the F-16 fly-by-wire airplane, four flight control computers are in the loop plus a polling computer that’ll turn off errant commands pronto I don’t know if that’s still true of the current versions of that airplane but … it was in the beginning. How a single point failure mode could have been allowed into the design is Boeings fault. But there’s fault to spread all around
This sort of blog is superb! I learn much from it all.
