Yep. The "AOA sensor disagreement" light is built into every cockpit, but it won't turn on unless the airline purchased a specific premium add-on. Boeing claims they initially didn't realize the light was bundled as an add-on, and then once they did realize, they decided it wasn't critical to the airplane's safety and just kept selling it as an add-on, which is... kind of alarming, to put it mildly. https://www.nytimes.com/2019/05/05/business/boeing-737-max-w...

> The "AOA sensor disagreement" light is built into every cockpit,

While technically true, that sounds a bit misleading considering that the AOA DISAGREE warning "light" is just a text indicator on the primary flight display: https://www.boeing.com/resources/boeingdotcom/commercial/737...

Shoot you’re right, I read “warning light” and just assumed. Thanks for the correction! On the other hand, it’s even weirder that Boeing didn’t bother fixing it if it was just a software patch...
Wow, that is remarkable.
