What's this?

My understanding is that 737 Max has 2 AOA vanes (sensors) only 1 signal

used by MCAS. I’m not sure if 1 is designated for MCAS or if the system alternates the sensor each flight. Simple (actually, simple is never “simple” 😉) might be to alternate AOA sensor each flight (If not done already) with a comparator upstream. To alert the crew or system controller to investigate and swap sensors or disable MCAS.

Agree, but at a more basic level it seems negligent to so totally rely on -- 81_Hokie 03/18/2019 11:05AM

Understand lots of redundancy on airplanes but I've read twice that there -- 81_Hokie 03/18/2019 12:38PM
