Minor correction about the Max8 that makes it worse.
Turns out the Max8 does have two angle of attack (AoA) sensors.
But the MCAS system only read from AoA1, and never validated it against AoA2. It was recieving info from AoA2, but never used it!
- marcosdumay 3y agoWhat do you do with 2 sensors? You can do something with 3 or more, but 2 are completely useless.

- Prickle 3y agoWhy would it be useless? Boeing's update for the Max8 MCAS (to make the FAA happy), was to make the system validate the two values. If there is a mismatch, the system outputs an error and MCAS will disable itself. In fact, that is literally one of the requirements set by the FAA to begin flying the Max8 again > FAA Airworthiness Directive approved design changes for each MAX aircraft, requiring input from two AoA sensors for MCAS activation, elimination of the system's ability to repeatedly activate, and allowing pilots to override the system if necessary.

- 0x457 3y agoMakes sense. Two sensors are about as useful as 2-node Consul cluster.
