> The MCAS system in the new 737-MAX's only have 2 AoA sensors That's pretty damning if true.

  This is what i was told (it was something like "they have 2 flight computers, and 1 AoA sensor hooked up to each"). The reddit thread linked from elsewhere says the same thing. The preliminary report on the Lion air crash (http://knkt.dephub.go.id/knkt/ntsc_aviation/baru/pre/2018/2018%20-%20035%20-%20PK-LQP%20Preliminary%20Report.pdf http://knkt.dephub.go.id/knkt/ntsc_aviation/baru/pre/2018/20...) says they replaced and tested the AoA sensor 2 days prior. They repeatedly refer to the AoA sensor using only singular nouns everywhere. Given the report says it was giving faulty data and that was used, the only way this can occur is either: 1. Their are multiple sensors and the software is broken 2. There is a single sensor Given all other data, i'm going with #2 :) Nobody has been enterprising enough to publish the MAX8 troubleshooting/etc manuals online, if they did, you could easily verify this.

    Some acquaintance of mine told me – which I really can't believe given the seriousness of aviation security – that there is in fact just one sensor. If true than that's preposterous.

      There are definitely at least 2. You can see them :)

        Still seems like at least one to few, no?

    Either way, this is insanity.

    From photos, there is (at least) one on each side. https://s3media.freemalaysiatoday.com/wp-content/uploads/2018/11/boeing-737-max-bloomberg-28112018.jpg https://s3media.freemalaysiatoday.com/wp-content/uploads/201... https://static.businessinsider.com/image/5be287c7b73c2846bb419884.jpg https://static.businessinsider.com/image/5be287c7b73c2846bb4...

      Yeah, this would line up with "1 sensor for each flight computer".
